Problem 18. Remaining time: 572:42 (minisec) (5 points) 350 Use 5 decimal places for intermediate calculations, and round your final answers to 3 decimal places. cec Suppose you want to test the claim the the paired sample data given below come from a population for which the mean difference is jay = 0. (a) Complete the table below. 71 85 55 82 70 91 54 68 d=x- y Use a 0.05 significance level to find the following: (b) The mean value of the differences d = (x - y) for the paired sample data d= (c) The standard deviation of the differences d for the paired sample data (d) The i Lost statistic Note: For the next part, your answer should use interval notation. An answer of the form (-co, a) is expressed (infty, al, an answer of the form (b, co) is expressed to, Infty), and an answer of the form (-co. a) U (b. co) is expressed (-Infty. njUjb. Infty). (s) The rejection region for the standardized test statistic:(1) Your decision for the hypothesis test: A. Do Not Reject How B. Reject How C. Roject H. D. Do Not Reject H, (o) Construct a 95% confidence interval for the population mean of all differences x - y
