A data set includes data from student evaluations of courses. The summary statistics are n=95, x=3.94, s=0.51. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. 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. The null and alternative hypotheses are H0: =4.00 and H1: 4.00 a) Determine the test statistic. (Round to two decimal places as needed.) b) Determine the P-value (Round to three decimal places as needed) c) State the final conclusion that addresses the original claim: (Reject / Fail to reject) H_0. There is (sufficient / insufficient ) evidence to conclude that the mean of the population of student course evaluations is equal to 3.50 (is / is not) correct
