Data from student course evaluations were obtained from the Uni- versity of Texas at Austin. The summary statistics are n = 436, x = 3.97, s = 0.55. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Do the results apply to the population of all students?
