A data set includes data from student evaluations of courses. The summary statistics are n= 90, x= 3.66, s= 0.53. Use a 0.01 significance level to test the claim that the population of student course evaluations has a mean equal to 3.75. Assume that a simple random sample has been selected. Identify the null and altemative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? OA. Ho: 3.75 OB.
