Stat 332 Sampling and Experimental Design: (Due: 12:29pm before class, Friday, Oct 19, 2012) Assignment 2 1. In the upcoming US presidential election this November, Florida is a key swing state that is very important in determining the outcome. Currently the Democratic candidate Barack Obama and the Republican candidate Mitt Romney are virtually tied in recent polls. For this question, you can use 9 million as our population size; this is approximately the total number votes in the 2008 presidential election in Florida. a) The latest poll asked 890 likely voters and found that the proportion of Florida residents likely to vote for the Democratic candidate is 47%, construct a 95% con? dence interval for this estimate under the SRSWOR. By the way, the support for Republican is 46%, and the rest are undecided. (b) If a news organization wants to conduct a SRSWOR survey to ? nd out the percentage of Florida residents supporting the Democratic candidate, what is the sample size needed to achieve a result which is accurate within 0. percentage point, 19 out 20 times? 2. We have 120 students in Stat332. (a) What is the total number of possible samples of size 10 under SRSWOR? (b) Suppose that among the 120 students of Stat332, 60 are male students and 60 are female students. We want to perform a STSRS (strati? ed simple random sampling) with male students and female students being two strata, and we want to survey 5 students from each stratum, what is the total number of possible samples? What is the ratio of the two numbers (STSRS/SRSWOR)? 3. Lohr (2010) Ch3, Q10 part a.Hard shell clams may be sampled by using a dredge. Clams do not tend to be uniformly distributed in a body of water, however, as some areas provide better habitat than others. Thus, taking a simple random sample is likely to result in a large estimated variance for the number of clams in an area. Russell (1972) used strati? ed random sampling to estimate the total number of bushels of hard shell clams (Mercenaria mercenaria) in Narragansett Bay, Rhode Island. The area of interest was divided into four strata based on preliminary surveys that identi? d areas in which clams were abundant. Then nh dredge tows were made in stratum h, for h = 1, 2, 3, 4. The acreage for each stratum was known, and Russell calculated that the area ? shed during a standard dredge tow was 0. 039 acres, so that we may use Nh = 25. 6 ? Areah . Here are the results from the survey taken before the commercial season. Estimate the total number of bushels of clams in the area, and give the standard error of your estimate. Stratum 1 2 3 4 Area Number of (Acres) Tows Made 222. 81 4 49. 61 6 50. 25 3 197. 1 5 Average Number of Sample Variance Bushels per Tow for Stratum 0. 44 0. 068 1. 17 0. 042 3. 92 2. 146 1. 80 0. 794 4. Assume the sample variance in Q3 is a good estimate for the strata variance, and we want a strati? ed sample size of n = 21. (a) Calculate the stratum sample sizes under proportional allocati on. (b) Calculate the stratum sample sizes under optimal (Neyman) allocation. (c) What are the values (approximately) of V (? st ) with sample size allocations of (a) and y (b), respectively? Compare these two variances and comment. . Foresters want to estimate the average age of trees in a stand. Determining age is cumbersome, because one needs to count the tree rings on a core taken from the tree. In general, though, the older the tree, the larger the diameter, and diameter is easy to measure. The foresters measure the diameter of all 1132 trees and ? nd that the population mean equals 10. 3. They then randomly select 20 trees for age measurement. The data can be downloaded as hw2q5. txt from course website on Waterloo Learn and read into R using d

Depend on you ( follow the instruction) - Essay Example ided that there was no way he could rationalize faith, and discovered another way to figure out the â€Å"truth† which was that of immediate experience which is based on imagination and intuition, not rationality. This is what is taught in the Sufi faith. Ghazali went to Syria to rediscover Islam, and went to live with the Sufi monks. Then he went on a pilgrimage to Mecca. It was during this pilgrimage that he was convinced that he was appointed to be a great reformer of the faith of Islam and his task was to inspire people. He went on to live in seclusion after this part of his life. He died in December 1111. Al Ghazali’s Alchemy of Happiness is one of the many books he wrote during his lifetime. This book shares what he thought of the significance of spirituality and religion in mankind’s quest for happiness. The book itself starts with the words, â€Å"He who knows himself is truly happy†. For Al Ghazali, everyone is perfect but that perfection is covered with the accumulation of worldly passions and animalistic desires. Thus, for him, mankind only requires â€Å"polishing† to achieve that perfection; to be polished is to â€Å"purify the heart from passion and resentment until, like a clear mirror, reflects the light of God†. For him, music and dance are perfect ways of achieving happiness. This is exemplified in the Sufi dervishes. Sufi dervishes are basically spinning, and spinning basically presents the idea that everything revolves around God and He is the center of every activity, as well as he surrounds every activity. As he said, â€Å"music and dance do not put into the heart what is not there already, but only fan into a flame of dormant emotions†. Also, his views on love and marriage proved to be philosophical as well. For him, marriage is an important part in our lives, mainly for the â€Å"worshippers to increase in number†. Although Al Ghazali may be chauvinistic at some point, stating that marriage is convenient because there will be someone to

Chevron Australia's Current Organisational Sustainability Protocol and Business Expansion - Case Study Example In fact, the chevron Australia stands out as one of the largest development alliances in the land. This is with the coming up of the gorgon gas project in particular as the single resource project in the land.

Historically, the company has been successful to produce a capacity of oil at the barrow island for about forty five years now. This is alongside other participants in the market hence declaring its capacity as high. The company has been structured into various departments all of which work out in the success of increasing energy in the country. A look at some of the projects for which the company has come about includes the gorgon project that has been mentioned earlier. This project in particular has been cited as one of the highly rated ones in Australia. The endurance of the project is through the greenhouse gas efficiency that the company has brought in place. On board the company has brought in capacity machines that enable the injection of carbon dioxide that enables the occurrence of the gas to the project. This is one of the sustainability measures that the company has taken into place. ... As such this is one of other sustainability measures that the company reveres. The participation of the company in a long time towards the venture of the offshore liquefaction mechanism brings into place the production of natural gas dating since the year 2008.

Business Research Essay Example | Topics and Well Written Essays - 2000 words

Business Research - Essay Example To quote Henry R. Luce, "Business more than any other occupation is a continual dealing with the future; it is continual calculation, an instinctive exercise in foresight." This extract alone tells us the importance of Business Research; the process of obtaining information. This paper, in its first part, will discuss the purpose and importance of business research in detail. It will also put light on how it is conducted and its strength and weaknesses. The second part of my paper will examine and analyze my own business research proposal.With globalization taking its toll in its truest sense, the business world has become more competitive than ever. New businesses are formed, the market keeps growing and changing, competition keeps increasing. In order to remain informed, it is absolutely essential for businesses today to carry out research about the market, about businesses and about anything that helps them to make informed decisions. Research is not only for scholars, but it is for anybody, any business that wishes to update its knowledge base.In the past, there was no such (or maybe just a vague) concept of information. Firms used to sit in their seats and guess which decisions will be successful and which will fail. Today, fortunately or unfortunat ely, guess work will not get most businesses far. It is important to have information before making the right decision. This is the most important aspect of business research; it facilitates in smart decision making.... If, for instance, a firm has some kind of knowledge about some new, relevant technology being developed in the market, and none of the other competing firms have this (because they don't carry out market research), this firm will be at a much better position in its market only because it carried out business research and thus was informed. Finally, some importance should be given to another, related and spawned off advantage; it helps in problem-solving. Business Research is a great tool used for solving any business problem. It makes it easier to see all sides of a problem and gives firms a 360 degree, comprehensive view of the problem at hand. How Business Research is Conducted There are many different ways that a business can conduct research. There is primary research, which means researching a question yourself by going out in the field and then there is secondary research, which means searching using second-hand or desk information. Different groups and sources have different names for methods. Essentially, they are all the same. The following primary methods are useful for our purpose: Appreciative Inquiry, Case Study Design, Focus Groups, Interview Designs, Questionnaire, Observations and Surveys. Some of these are qualitative, for example, interviews while some are quantitative.Additionally, business research is conducted as a process. There are many different stages in the process of business research. It starts off with formulating a research question, that is, the focus of the research must be specified here. Then there is the hypothesis that gives your predictions and analysis of the answer to you research question. To test this hypothesis, some kind of a method (discussed earlier)

Inventory Paper Essay Example | Topics and Well Written Essays - 500 words

Inventory Paper - Essay Example The modern context, nonetheless, opposes the form of influence that entails coercion. Instead, effective leaders seek to build relationships with their followers. In fact, just like Blake with his TOMS idea for providing shoes to the children in Argentina, modern day leaders need to put the interest of their followers before theirs. They then forge a win-win situation for both parties. Despite all leadership not being equal, such successful leaders exude unique leadership styles that identify them and seek to lead by example, having developed their inner selves first before instilling the same in their followers. This activity has been useful in appreciating my leadership style. I am democratic and would always seek to have the will of the people prevail. Perhaps, this style is supported by the activity’s acknowledgement of the need for selflessness for success as a leader. In most cases, I seek to lead by example, always doing what I would expect my followers to do. This has made me to cause people to take up tasks they never imagined they would undertake. I am not coercive. This could be a failure on my part because as learnt from the activity, some coercion could help a leader realize the set objectives. However, care should be taken to ensure that a balance between coercion and free will by followers is reached. By being democratic, I have had the undesirable will of the people carry the day. There was this one day when I was charged with the finances for our sports cheering team that accompanied players to a tournament. I proposed that we share the allowances at the end of the tournament. The cheerers wanted it before and I did as they wished. By the time the games started, they had spent all the money and some were even hungry already. They failed to cheer our team well, perhaps the reason we were beaten. Thus, I do not support the postulate from this activity that a successful leader should be defined by a specific style. Instead, a leader should
