(1 point) Suppose you want to test the claim the the paired sample data given below come from a population for which the mean difference is # = 0. X 65 59 80 73 52 61 82 y 75 56 92 92 73 94 67 Use a 0.01 significance level to find the following: (a) The mean value of the differnces d for the paired sample data d = (b) The standard deviation of the differences d for the paired sample data Sd = (c) The t test statistic 1= (d) The positive critical value 1= (e) The negative critical value (f) Does the test statistic fall in the critical region? OA. No OB. Yes (9) Construct a 99% conficence interval for the population mean of all differences x - y.
