A data set includes data from student evaluations of courses. The summary statistics are n=92, x=3.61, 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. =/= Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. (reject/fail to reject) H0. There is (sufficient/not sufficient) evidence to conclude that the original claim that the mean of the population of student course evaluations is equal to 3.75 (is/is not) correct.
