(8 points) Suppose you want to test the claim the the paired sample data given below come from a population for which the mean difference is d = 0. Use a 0.01 significance level to find the following: (a) The mean value of the differences d for the paired sample data d= = (b) The standard deviation of the differences d for the paired sample data 8d (c) The t test statistic = I 87 68 64 87 83 56 83 y 67 66 74 56 84 63 66 (d) The positive critical value t = (e) The negative critical value t = (f) Does the test statistic fall in the critical region? A. Yes B. No (g) Construct a 99% conficence interval for the population mean of all differences x - y. <Hd <
