A data set includes data from student evaluations of courses. The summary statistics are n=95​, x=4.19​, s=0.55. Use a 0.01 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. 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..
