mber This will jus. A data set includes data from student evaluations of courses. The summary statistics are n= 88, x=4.09, s 0.66. 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. What are the null and alternative hypotheses? O A.

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p, and p, at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent random samples. Claim: P1 = P2, a = 0.10 Sample statistics: X1 = 108, n, = 128 and x, = 32, n, = 195 ... Ha: P1 7 P2 O E. Anormal sampling distribution cannot be used, so the claim cannot be tested. Find the critical values. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The critical values are - z, = 1.28 and zo =1.28 (Round to two decimal places as needed.) B.
