Chapter 14, Problem 30(choose chapter or problem)
Exercises 29 through 32 refer to the following story: The dean of students at Tasmania State University wants to determine how many undergraduates at TSU are familiar with a new financial aid program offered by the university. There are 15,000 undergraduates at TSU, so it is too expensive to conduct a census. The following sampling method is used to choose a representative sample of undergraduates to poll. Start with the registrars alphabetical listing containing the names of all undergraduates. Randomly pick a number between 1 and 100, and count that far down the list. Take that name and every 100th name after it. For example, if the random number chosen is 73, then pick the 73rd, 173rd, 273rd, and so forth, names on the list. (The sampling method illustrated in this survey is known as systematic sampling.)a) Find the sampling proportion. (b) Suppose that the survey had a response rate of 90%.Find the size n of the sample.
