![A data set includes data from student evaluations of courses. The summary statistics are n=94, x=4.08, s=0.64. Use a 0.05 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.
