A data set includes data from student evaluations of courses. The sijmmary statistics are n=97, x= 3.58, s = 0.52. 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 à 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 O B. Ho: H#3.75 Hi>3.75 H,:u=3.75 OC. Ho: H=3.75 O D. Ho: H=3.75 H,:u#3.75 H,:u<3.75
