A data set includes data from student evaluations of courses. The summary statistics are n = 90, i = 4.07, s = 0.59. 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 nal conclusion that addresses the original claim. <:> What are the null and alternative hypotheses? O A.
