Using the data in Exercise 2, test the hypothesis that the mean numbers of page views from the two websites are the same. You may assume that the number of page views from each website follows a Normal distribution.

Website 1 Website 2 n = 80 7.7 pages S = 4.6 pages n2 = 95 ½ = 7.3 pages Sz = 4.3 pages %3D

a) Calculate the P-value of the statistic, knowing that the approximation formula gives 148.0 df.

b) Calculate the P-value of the statistic using the rule that df is at least min (n₁ - 1, n₂ - 1).

c) What do you conclude at α = 0.05?

Website 1 Website 2 n = 80 7.7 pages S = 4.6 pages n2 = 95 = 7.3 pages Sz = 4.3 pages %3D
