A data set includes data from student evaluations of courses. The summary statistics are nequals 91, x overbar equals4.17, sequals 0.69. Use a 0.10 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. What are the null and alternative hypotheses? A....

Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally! distributed populations. Also assume that the population standard deviations are equal (0, 0), so that the standard error of the difference between means is obtained by pooling the sample variances.
