7.Suppose that University of Pennsylvania advertises that its average class has 35 or fewer students. Now after the pandemic there was concern that with budget issues as a result of the pandemic that there would be an increase in class sizes and would like to test the claim. A random sample of 38 classes was selected and the average class was found to be 36.9 students. Assume the standard deviation for class size is 8 students. Using α =0.05 , answer the following: Does the student organization have enough evidence to refute the college’s claim? Determine the p-value for the test.
