Suppose a paired random sample of size 25 yielded the following information: D= 13.42, s3 = 2.53. Test the hypothesis that the difference of the two population means is less than or equal to 13 with the alternative that the difference is greater than 13. Use a = 0.05. The following answers" have been proposed. (a) Since D-13 = 1.32 > 1.71, we do not reject the null hypothesis. We might have made the type II error. (b) Since D-13 = 1.32 > 1.71, we do not reject the null hypothesis. We might have made the type I error. D-13 (c) Since = 1.32 > 1.299, we reject the null hypothesis. We might have made the type I error. (d) Since D-13 = 1.32 > 1.299, we reject the null hypothesis. We might have made the type II error. Spyn (e) None of the above. The correct answer is (a) (b) (c) (d) (e) N/A (Select One)
