A data set includes data from student evaluations of courses. The summary statistics are n = 86, x = 3.58, s = 0.57. Use a 0.05 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 alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: H # 3.75 B. Ho: H= 3.75 Hy: H = 3.75 Hy : u # 3.75 O C. Ho: H = 3.75 OD. Ho: H= 3.75 Hy: H 3.75 Determine the test statistic. (Round to two decimal places as needed.)
