A university has 20,000 students. You have drawn a simple random sample of 600 students from this university. In this sample of 600 students, 270 students purchased books from www.amazon.com in 2018. At a 99% level of confidence, test the null hypothesis that not more than 8000 out of the 20,000 students at this university purchased books from www.amazon.com in 2018.

Suppose we wish to organize a rock concert at a university campus. The campus has 20,000 students. Our costs will be exactly recovered if 4,000 students attend the concert; we will make a profit if more than 4,000 students attend. In a simple random sample of 100 students, 30 students will attend the concert. At a 95% level of confidence, test the null hypothesis that not more than 4,000 students will attend the concert.

A simple random sample of 18 male students at a university has an average height of 70 inches. The average height of men in the general population is 69 inches. Assume that male height is approximately normally distributed with σ = 2.8 inches. Conduct a two-sided hypothesis test to determine whether the male students have heights that are significantly different than expected. Show all hypothesis testing steps.

A random sample of 200 students was drawn from a large university. It was found that 73 students in this sample live in off-campus apartment. Construct a 90% confidence interval for the proportion of students in this university that live in off-campus apartment. Use normal approximation in this question. You can also take a look at Wilson score interval.

Two different simple random samples are drawn from two different populations. The first sample consists of 30 people with 15 having a common attribute. The second sample consists of 1900 people with 1379 of them having the same common attribute.
