Confidence Intervals Mail Print Twitter Facebook Date Assigned: November 17, 2006 Date Due: November 29, 2006 (work independently) Several factors are involved in the creation of a confidence interval. Among them are the sample size, the level of confidence, and the margin of error. The Context: Suppose a number of students are selected randomly from a student body of 20,000 and they are each given shots to prevent a certain type of flu. Suppose that 75% of them do not get the flu. Analysis: Decide which of the following statements are true and which are false and explain the basis for your decision. A. For a given sample size, higher confidence means a smaller margin of error. This statement is false. Results 1, 2, and 3 all have a sample size of n = 800. As the confidence level goes up the left endpoints become smaller and the right denpoints become larger. That means the widths of the intervals become larger as the confidence level increases. Since the margin of error is half the width of the interval, the margin of

information about a sample. One very vivid application is currently in the news: polls attempt to determine the way a population will vote by examining the voting patterns within a sample. The idea of generalizing from a sample to a population https://www.math.lsu.edu/~madden/M1100/week12goals.html is not hard to grasp in a loose and informal way, since we do this all the time. After a few vivits to a store, for example, we notice that the produce is not fresh. So we assume that the store generally has bad produce. This is a generalization from a sample (the vegetables we have examined) to a population (all the vegetables the store sells). But there are many ways to go wrong margin of or to misunderstand the meaning of the data obtained from a sample. How do statisticians conceive of the process of drawing a conclusion about a population from a sample? How do they describe the information that is earned from a sample and quantify how informative it is? How much data do we need in order to reach a conclusion that is secure enough to print in a newpaper? Or on which to base medical decisions? margin of error These are the questions that we will address this week. The simplest example arises when one uses a sample to infer a population proportion. We can give a fairly complete account of the mathematical ideas that are used in this situation, based on the binomial distribution. My aim is to enable you to understand the internal mathematical "clockwork" of how the statistical theory works. Assignment: Read: Chapter 8, sections 1, 2 and 3. For the time being, do not worry about pasages that contain references to the "normal distribution" of the "Central Limit Theorem" . (Last sentence on page 328, last paragraph on p. 330, first paragraph on p. 332.) Also, do not worry for the time being about the examples in section 3.2. Review questions: pages 335 and 351. Problems: p. 336: 1--8, 11, 12, 13, 14. p. 351: 1--12, 13, 16, 21, 22. In-class: p. 337: 20. EXTRA CREDIT: Find an article in the New York Times that describes a poll. The New York Times provides readers with a very careful explanantion of margin of error and level of confidence; find their explanation either in an issue of the paper or on the paper's web site, and report on it. Compare with the information provided by other papers. Vocabulary: Parameters and statistics: population mean: the average value of a variable,
