WEEK 6 SQ - Essay Example Twenty packages are inserted in a box for shipment. To test the weight of the boxes, a few were checked. The mean weight was 20.4 pounds, the standard deviation 0.5 pounds. How many boxes must the processor sample to be 95 percent confident that the sample mean does not differ from the population mean by more than .2 pounds? Ch.10-6 The MacBurger restaurant chain claims that the waiting time of customers for service is normally distributed, with a mean of 3 minutes and a standard deviation of 1 minute. The quality assurance department found in a sample of 50 customers at the Warren Road MacBurger that the mean waiting time was 2.75 minutes. At the .05 significance level, can we conclude that the mean waiting time is less than 3 minutes? The p-value is the probability of finding a z value less than -1.77. From Appendix D, the probability of a z value between zero and -1.77 is .4616. So the p-value is .0384 (0.5000 – 0.4616 = 0.0384). Ch. 10-18 The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart. The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using the .10 level of significance, can we conclude that the assembly time using the new method is faster? Ch. 11-24 Clark Heter is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the afternoon shift than on the day shift. A sample of 54 day-shift workers showed that the mean number of units produced was 345, with a standard deviation of 21. a sample of 60 afternoon-shift workers showed that the mean number of units produced was 351, with a standard deviation of 28 units. At the .05 significance level, is the number of units produced on the afternoon shift larger? Ch. 11-38 Two boats, the Prada

A Smart Action Plan

A Smart Action Plan After I had started my first year at University I realised that if I want to become a successful student it is crucial to develop time-management skills. It is based on identifying our goals, prioritising and listing them in order to help us achieve the best result. We also need to identify our strengths, look at our work and think how we could improve it to get a better result in the future. We can do so using a diary or personal organiser. Time-management skills are very important because if we know how to organize our time properly, we can carry out more and meet deadlines. It is important to start with setting our priorities because sometimes there is no time to complete all of them. We need to be aware that some of them might take longer than we expected so we should write somewhere what we want to do and when we want to do it. Resources: We should start with identifying our goals and priorities. When doing so, we need to be realistic and definite about them. We must precise what needs to be done, how and when. Then, it is recommended to start keeping an academic diary or a personal organizer where we can write in everything we do (such us important dates or study activities). It will help us to look at the way we work and identify where further improvements can be made. (Oxford Brookes University) To take the most out of the diary we should always carry it with us and keep it up to date. It is also recommended to check it many times a day and add new tasks straight into it. The last step is to identify how we spend the time in order to see if we use it productively. We need to list the work we have to do and precise the amount of time we want to spend on carrying out particular tasks. The most important things should be highlighted or stared that can be easily seen, where the least important ones should be written in a pencil so we can change or remove them easily. (Cottrell S., 2003) Reflective comment: The first thing I did in order to improve my time-management skills was doing some background reading. I used a chapter of a book recommended by my tutor as well as some online resources. It gave me understanding of which steps should be taken in order to became successful. I started with identifying my goal, which was preparing a good set of notes for my oncoming exam. Then I started writing in a diary activities I was planning to do. The most important ones I wrote in using a pen (such as searching for material for my notes) and less important in pencil (like going to the store or meeting someone). The following, I highlighted the most important one so every time I opened my diary it was the first thing I saw. It was a reminder of what is need to be done. Then I identified how much time I want to spend on these tasks. This technique helped me a lot with organizing my time. Now I know that before my problem had lied in spending too much time on unimportant things, therefore I had not had too much time to complete everything I wanted. After getting into a routine of planning my time and studying at set times I am more systematic and precise. References: Cottrell, S. (2003). The CREAM strategy for learning.

Theme 2: Developing an academic writing style Theme: Developing an academic writing style Activity: As an international student I am even more aware of the importance of well-developed writing skills. It is crucial because the better our skills in writing are, the more flexible we can be while writing. There is no definitive definition what an academic writing style is but there are five technical qualities that help making a piece of writing academic. It needs to be Formal, Others, Cautious, Succinct, Impersonal (FOSCI). However, we need to start with developing a habit of writing which is fundamental when working on academic essays and writing under time and exam conditions. Resources: First what we should do is build up our confidence in writing. We can start with writing one world several times and find out our writing style. When a habit of writing is already developed, we need to get used to writing continuously. To do so, it is recommended to try to write for at least five minutes, whatever the content is. We can use this piece of writing in next step where we need to rewrite already done piece of work and add the new detail to it (such us information, opinion). Further step is focused on rewriting that piece and playing with what we have already written (changing the words, the orders). Then comes organising material where we highlight each idea in a different colour. Then rewriting the passage so colours are grouped. It is also important to know how to overcome writerà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s block. We can for example write in pencil (it will remind us that this is a draft so mistakes are allowed and nobody needs to see it). We can also write on th e computer where we can use a spellchecker. (Cottrell S., 2003) Reflective Comment: I decided to improve my academic writing skills because I know how it can affect my grades. I applied this technique in several steps. I started with writing in pencil about my first day in Scotland to get used to writing. I was doing it constantly for 5 minutes. Then, I read it and changed some words and added more details to it. The following, I have rewritten it and checked the grammar and spelling mistakes. Next, I again rewritten the piece but this time in different colours, each relating to a different section: what I saw, how I felt, what I wanted to do. While rewriting the last draft, I was grouping sections together so it looked all tidied up and therefore easier for the reader to understand. The final piece I have rewritten on my computer and checked for unnoticed spelling and grammar mistakes. This technique was time consuming as required rewriting each piece of work several times but it is really worth it. The time I spent on getting used to using this technique took me nearly two weeks but it was really worth it. It paid me off with better-quality and enriched in details work in later days, when I was working on my coursework. References: Cottrell, S. (2003). Writing for university. In: The Study Skills Handbook. 2nd ed. New York: Palgrave Macmillan Ltd. p143-148. 4. Theme 4: Self-knowledge Theme: Self-knowledge Activity: In order to take some more control in my life and improve my performance I am going to improve my self-knowledge skills. Self-knowledge is about knowing ourselves intimately. It means knowing and understanding our inner feelings, motivations, weaknesses, strengths, motivations, desires, skills, etc. and how they affect our behaviour (Ong T., 2004). This is the starting point when developing a skill and in achieving set goals. When is well-developed, increases our confidence and chances of success. It allows us to turn our weaknesses into strengths and present ourselves well to others, develop confidence or set our priorities for creating new skills. Resources: It is essential to know where are we starting from. Therefore we need to estimate to ourselves what we want to improve and how are we going to improve it. There are many ways of developing it, such as self-evaluation questionnaires, psychometric tests, reflective journals or using tutor feedback on our work. All of these are valuable because are giving people an objective view of how they behave and compare in outlook with others. It is also recommended to put ourselves in new situations, go to new places, experimenting new hobbies (exploring unfamiliar roles and situations à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ we often discover new things about ourselves when were in unusual situations, or facing new challenges. (Mind Tools, 2012) It is also essential to write every day about our thoughts, feelings and emotions because regular writing improves self-knowledge (Cottrell S., 2003). It builds our emotional fluency and helps to find out things we need to work at in order to improve our performance. Reflective comment: To understand more about myself I am going to do a self-evaluation questionnaire or psychometric test. It will give me basic understanding of who I am and what should I work at, what my traits and preferences are. Then, I am going to apply the second step. I will present myself with new situation. I am planning to go the gym to attend aerobic class by my own. Because I had never been at this place before, I will be surrounded by strangers. I hope this experience will help me to discover new things about myself and how I deal with some of the aspects of my life. The following, I will write in my diary about my feelings of that experience and reflect on that. I believe that the collection of writing will help me understand the range of emotions I have experienced. I believe that out emotional self-analyse is a key-point in order to improve our performance. References: Mind Tools. (2012). Coaching to Develop Self-Awareness.

Theme 4: Becoming a reflective practitioner Theme: Becoming a reflective practitioner Activity: To improve my overall performance it is important to reflect on our work. Therefore I decided to improve my reflective practise skills. It is imperative because it helps us to better understanding of the work we are doing when we do it as well as after we have done it. It is critical evaluation of all the available evidence. Its purpose is reflecting on what went wrong and how we could possibly improve it and reflecting on what went good and thinking why it went good. It improves our evaluation skills, action plan for success as well as develops answers to our difficulties. Resources: Our performance is likely to increase when we know how to reflect on our work. Things like studying are going to improve when we look at things such as our motivation, skills needed, things that disturb us and so on. There are several methods of developing the act of reflection while studying: writing a learning journal, using the self-evaluation questionnaires, keeping portfolio, using the tutorsà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ feedback on our work or filling the progress sheets. In order to reflect on personal, academic and professional development we can start off with writing down anything we can reflect on. Such as our feelings about our friends or people we work with, the things we struggle with or the things we want to achieve. How everything we have learnt relate to real life or things we want to change. Writing our emotions down will help us to simplify our inner feelings, to work out plans and to focus on our development. The final step is reflecting on what we have learn t from the previous situation to the next one. (Cottrell S., 2003) Reflective comment: To improve my overall performance as a student at the University I am aware that it is crucial to start reflecting on my work and see what I do wrong or well. After doing some background reading, I decided to improve my reflective practise skills. To do so, I am going to use my copies of the assessments with the tutorsà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ comments on them. Then I am going to write down all the mistakes I have done and reflect on them, asking myself what I did wrong and why I did it and being focused on what skills I need to avoid this next time and how am I going to achieve this. I believe this will bring me a wider understanding of my mistakes and allow me to see what I could possibly improve and change to get a better grade. In the next step I am going to be focused on filling the progress sheets for each module. I believe this activity will enhance my motivation because it will allow me to see the progress I am making and see the things I did wrong and therefore this will be helpful in avoiding them. In my final step will be reflecting on what I have learnt from the previous situation and applying it to the next one. I think this step is very important because when we are aware of what had gone possibly wrong, we can avoid making the same mistakes next time, improving our work and performance.

Genetic Engineering Essay -- Genetic Alteration Manipulation

Genetic Engineering of Humans Human genetic engineering in the world today has become an issue because of its many positive uses and its probable consequences. There is no denying that it could be incredibly useful for preventing diseases such as cancer and others before we are even born. But, with this also comes the ability to give children genes before their born that will give them talent to run faster, jump higher, use more of their brain that will severly distinguish them from the rest of society. Imagine growing up and you are the best athlete in your high school, you can out perform anyone you come against. You are commended on your work ethic but he question that comes up most often is â€Å"How do you do it?† You begin to think about this question. What do I do that’s different from everyone else? Is it a talent, or is there something that separates you from everyone else. Your parents have no athletic skill at all, so where is all this skill coming from? Then you bring this up wi th you parents and they let you in on startling news. When you were born you parents had your genes altered to make you more athletic. How would you feel? The idea of genetic alteration of humans for purposes such as increasing physical is a worrisome topic. It is a hard topic to address and dismiss as a bad idea because there are many good applications for this procedure. The idea of curing humans of diseases before birth is an amazing thing to think about. This poses a bright future for mankind but it also includes a distressing idea. The fact that humans can alter the fate that god intended us is scary. Humans were not meant to alter their future, but throughout history they have. Being able to cure imperfections in humans see... ...ld cause many problem in our society. Also morally is it right for us to be picking and choosing what talents a child will have before they are even born. It should be up to the child to build their skills in an area that they are genuinely interested in. They should not be pressured to be a runner because they ability to run faster and farther than your average man. It is wrong to predetermine a childs fate. What makes a child unique if he did not determine his uniqueness on his own. Genetic engineering is an issue that is rapidly approaching us as a problem we will have to deal with. Is it ok for me to choose what my child is good at? Is it ok for me to change the person that god intended my child to be? Many people are worried about the stage genetic engineering is at and all the problems it could cause but we still may have some time to think about it.

Investigatory Project—Lever

A more proficient use of lever: A heavier lift Introduction A. Background of the study Buildings, infrastructures and a like were built using the help of machines. But have you ever ruminated how ancient structures like pyramids were built? Simple machines figured it out. Simple machines are any device that only requires the application of a single force to work. It is a tool used to make work easier. It gives mechanical advantage. This means that if you use a lever and the mechanical advantage it provides, you can lift an object that's much heavier than you are because the lever multiplies your effort. Lever, it is often used to move heavy loads with less effort. It is a rigid object that is used with an appropriate fulcrum point to multiply the mechanical force that can be applied to another object. B. Statement of the problem A study on the proficiency of lever in lifting heavy objects. Specific Objectives †¢To build a tabletop lever and investigate how changing the length of the effort arm affects the amount of effort it takes to lift an object. †¢To discover other factors that can affect the proficiency of lever. 2 E. Review of related literature The following definitions are the terms and concepts regarding the said investigatory project. Simple machines is any device that only requires the application of a single force to work. It is a tool used to make work easier. lever magnifies force or velocity. It is often used to move heavy loads with less effort. It is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object. Fulcrum , the support about which a lever turns. Beam, The bar of a balance from which weighing pans are suspended. Parts of the lever (in the experiment, still undefined) Effort end †¢Effort arm †¢Load end †¢Load arm *The First Class Lever, Second Class Lever and the Third Class lever. The only difference between them is the location of the fulcrum. *Levers help you move items that are very heavy. In the First Class lever the fulcrum is located in the middle. The load is on one end and the force is on the other. (crowbar) Second Class the fulcrum is on the end, the resistance force, the load, is in the middle, and the effort is at the other end. (wheelbarrow) The Third Class fulcrum is on the end of one side, the effort force is in the middle, and the resistance force, the load, is at the the top. baseball bat) *Levers are easy to spot because they help us in our lives. Some examples are: see-saw, claw hammer, crow bar, bottle opener, Piano keys, and car jacks.

Materials and equipment †¢Ruler (with centimetres) †¢Plastic bag †¢Masking tape †¢Scissors †¢Pencil †¢Soap box with soap in it †¢Marbles (in same sizes) B. Procedure To start this project, you will need to build your lever. The ruler will be the beam for the lever. Tape a bar of soap to one end of the ruler. The soap is the load you will be trying to lift. Next you will need to construct a container out of your plastic bag to hold the marbles in. The bag and the marbles you'll place in the bag will be the effort. As you add more marbles, you are increasing the weight in the bag and thus, the effort until you eventually have enough effort to lift the soap bar. Put a piece of tape approximately 1 centimeter (cm) from the top of a plastic bag . Fold the taped part in half. Using a pair of scissors, cut a slit long enough to allow the ruler to slip through. Slip the free end of the ruler into the slit. Tape the bag to the ruler so it does not slide around. Be careful not to tape the bag closed, as you will need to add marbles in it. tape pencil to the edge of a table. Place your lever on the fulcrum. The bar of soap should be resting on the table, and the bag for the marbles should be dangling over the edge of the table. Position the ruler so that the length of the effort arm is 6 cm. You can use the markings on the ruler to measure 6 cm. Add marbles to the bag, one at a time, until the bar of soap lifts off the table. Continue increasing the effort arm length by 2-cm increments until the measures 24 cm. Materials and Equipment †¢Metric ruler (preferably one that is stiff and has centimeter markings) †¢Plastic sandwich bag (1) †¢Tape (preferably masking tape) †¢Scissors †¢Pen or pencil †¢Bar of soap (still in its packaging) †¢Pennies (approximately $3 worth; alternatively, marbles, beans, or some other small numerous item will work) †¢Lab notebook †¢Graph paper Experimental Procedure 1. To start this project, you will need to build your lever. The ruler will be the beam for the lever. Tape a bar of soap to one end of the ruler. The soap is the load you will be trying to lift. 2. Next you will need to construct a container out of your plastic bag to hold the pennies in. The bag and the pennies you'll place in the bag will be the effort. As you add more pennies, you are increasing the weight in the bag—and thus, the effort—until you eventually have enough effort to lift the soap bar (the load). a. Put a piece of tape approximately 1 centimeter (cm) from the zipper part of the top of a plastic sandwich bag. Do this on both the inside and the outside of one side of the plastic bag. See Figure 2. a. below. b. Fold the taped section in half, width-wise. Using a pair of scissors, cut a slit long enough to allow the ruler to slip through. See Figure 2. b. below. c. Slip the free end of the ruler (the effort end) into the slit. Tape the bag to the ruler so it does not slide around. Be careful not to tape the bag closed, as you will need to add pennies inside it (the effort). 1. ncrease the length of the effort arm by 2 cm (total length should now be 8 cm) and repeat step 5 again. Did it take more or fewer pennies to lift the load? Record your findings. 2. Continue increasing the effort arm length by 2-cm increments and retrying the experiment until the effort arm measures 24 cm. Don't forget to record all the data in your data table. 3. Analyze your data. You can make a line graph with the length of the effort arm on the x-axis and the number of pennies it takes to lift the load on the y-axis. Do you see a pattern? What happens when you double the distance? What happens when you quadruple the distance? To use the computer to make your graph you can visit the Create A Graph website. . You are trying to determine the relationship between two variables: the effort (# of pennies) it takes to lift the load (bar of soap) and the length of the effort arm, so choose the XY graph. b. Select the Data Tab, fill in: ?The graph title ?X-axis label (remember, the x-axis is the length of the effort arm) ? Y-axis label (remember, the y-axis is the number of pennies is takes to lift the load) ? In the Data Set box, tell the program you have 12 data points. ?For each point, fill in the length of the effort arm (x) and the number of pennies (y). So, point 1x would be 6 since you took your first data reading when the effort arm was 6 cm long. Point 1y would be the number of pennies, recorded in your data table, that it took to lift the soap bar at an effort arm length of 6 cm. ?You can use the remaining options to customize the font styles and colors of your chart. c. When you are done, print it out. Variations †¢What happens if you double the load by adding two soap bars? Does the effort (number of pennies in this science project) required to lift the load also double? What if you triple or quadruple the load? Use a kitchen scale to determine how much the load (soap bar) weighs and how much the effort (number of pennies needed to lift the soap bar) weighs. Can you use this information to calculate how much effort it would take to lift you? †¢In your background research you learned that there were several classes of levers. In the project above, you built a class 1 lever. Try building a class 2 lever, too. Compare t he class 1 and 2 levers. Do they require the same effort to lift the load? Remember to keep the distance between the fulcrum and the effort end the same when comparing the levers!

Fostering Ethical Behavior Essay

Ethical conduct in today’s work environment is extremely important as it not only affects the climate of the workplace but can also make a major impact on the output of the employees who work for you. As Kreitner and Kinicki state, â€Å"Improving workplace ethics is not just a nice thing to do; it also can have a positive impact on the bottom line† (Organizational Behavior, 2009, p. 25). But the discussion on how to foster more ethical conduct can oftentimes be a tricky question to answer. First, my firm belief is that you have to start from the top of an organization and work down. If a CEO or upper level manager acts unethically in his/her practices then how can you expect another employee to not react in the same manner? â€Å"Managers are potent role models whose habits and actual behavior send clear signals about the importance of ethical conduct. Ethical behavior is a top-to-bottom proposition†¦Ã¢â‚¬  (Organizational Behavior, 2009, p. 25). Secondly, an organization should maintain a strong and respected code of ethics that all employees would be required to adhere, train and reinforce in the workplace. Unethical behavior to get ahead can be a poison to any organization. â€Å"Behavior that is reinforced tends to be repeated, whereas behavior that is not reinforced tends to disappear. Ethical conduct too often is ignored or even punished while unethical behavior is rewarded. † (Organizational Behavior, 2009, p. 25). It should be the number one goal of any top management to foster a working environment where ethical behavior is rewarded and I feel that leading by example from the top down will result in a positive outcome in the workplace.
