Suppose we wish to testthe following hypotheses for the data:
Calculate the mean andthe standard deviation s of the data asabove:
(A)Compute the appropriate test statistic for testing (show all work).
(B)Determine the critical value for a = 0.01.
(C)Test using the traditional/classicalmethod.
(D) Statethe decision based on the results of the test.
(E) Hadyou used the p-value method of hypothesis testing, what would thep-value have been?

Explanation / Answer
Note: You have not stated the hypothesis which needs to betested. mean of the data given, x = 47.03 standard deviation for the data given, s = 9.17 for a = 0.01, p -value for a two tail distribution =2.58 (from z table)
