Using the table given below, determine the lower- and upper-tail critical values for the Wilcoxon rank sum test statistic T, in each of the following two-tail tests. a. a = 0.10, n=8, n2 - 9 b. a = 0.05, ny = 8, n. = 9 C. c = 0.01, n = 8, n. = 9 d. Given your results in (a) to (c), what do you conclude regarding the width of the region of non-rejection as the selected level of significance a gets smaller? Click the icon to view the table of critical values for the Wilcoxon rank sum test. a. The lower-tail critical value is and the upper-tail critical value is (Type whole numbers.) b. The lower-tail critical value is and the upper-tail critical value is 1 (Type whole numbers.) c. The lower-tail critical value is and the upper-tail critical value is (Type whole numbers.) d. The width of the region of non-rejection as the selected level of significance a gets smaller
