A committee surveyed 173 students from a large university campus and found that 53 of them participated in varsity sports. (a) Based on the survey results, construct and interpret a 95% confidence interval for the proportion of students who are varsity athletes. (b) Based on the survey results, test the claim that more than 25% of students are varsity athletes. Use alpha=0.01α = 0.01. Show all work.

Here

a) 95% confident that the proportion of students who are varsity athletes is between 0.2377 and 0.3750.

b) Accept Ho at 0.01 level of significance.

I.e. There is not sufficient evidence to claim that more than 25% of students are varsity athletes.

Many University campuses sell parking permits to their students allowing them to park on campus in designated areas. Although most students complain about the relatively high cost of these permits, what annoys many of these students even more is that after having paid for their permits, vacant parking spaces in the designated lots are very difficult to find during much of the day. Many end up having to park off campus anyway, where permits are not required. Assuming the University...

A large university provides housing for 10 percent of its graduate students to live on campus. The university’s housing office thinks that the proportion of graduate students looking for housing on campus may be more than 0.10. The housing office decides to survey a random sample of graduate students, and 62 of 481 say that they are looking for housing on campus. At a=.05, is there evidence to support the housing office’s suspicion?

A Rutgers University study found that many high school students cheat on tests. The researchers surveyed a random sample of 4500 high school students nationwide; 74% of them said they had cheated at least once. a) Create a 90% confidence interval for the level of cheating among high school students. (Use your calculator to create this interval. Do not do the calculations by hand.) b) Interpret your interval. c) Would a 95% confidence interval be wider or narrower? Explain.
