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.
