A data set includes data from student evaluation of courses. The summary statistics are n=91, x=3.93, s=0.61. 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.
