In a sample of 200 UM students, 170 students reported listening to Eminem daily. In a similar sample of 150
OSU students, 107 students reported listening to Lizzo daily.
a. Do the same proportion of UM and OSU students listen to Lizzo every day? Test at 98% confidence
b. If you want to create a 90% confidence interval with a margin of error of .09, and want to include 1.5
times as many OSU students as UM students, how many people do you need from each school?

A recent survey of 31 students reported that the average amount of time they spent listening to music was 11.5 hours per week, with a sample standard deviation of 9.2 hours. Which of the following is a 90% confidence interval for the mean time per week spent listening to the radio? Is this confidence interval for a population mean or population proportion? When do you use a z-test and when do you use a t-test?

A local university wants to conduct a sample of 200 students out of 6000 students. We can assume that the university maintains a good roster of all registered students. (1) how would you select the 200 students(a) using simple random sample method and (b) systematic sampling method? (2) suppose that the university administration wants to make sure in particular students who major in music (a small department with only 8% of students major in music)be adequately included in your sample,...

A random sample of 200 students has been randomly collected to understand the distribution of a schools favourite fruit in Europe. How do I identity the measures of statistical distribution? The fruit given is Banana - 50 students; Orange - 50 students; Apple - 40 students; and Other - 60 students; to make the sample size of 200 students.

Include diagrams and calculations for the following: A.In a recent random sample of 200 students at a large university who were recently forced to watch their lectures on-line, 65 indicated that they preferred on-line lectures as opposed to the normal in-class lectures. Estimate, with 90% confidence, the true proportion of all students at this large university who prefer on-line lectures. (Include a concluding statement similar to concluding statements from examples already covered in class.) B.In a random sample of...
