Using the table given below, determine the lower- and upper-tail critical values for the Wilcoxon rank sum test statistic T1 in each of the following two-tail tests. a. (1:13.10, n1=9,n2 =9 b. 01:005. n1 =9, n2 =9 C. 0t=0.01, n1=9,n2 :9 d. Given your results in (a) to (o), what do you conclude regarding the width of the region of non-rejection as the selected level of significance or gets smaller? g 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 (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 V as the selected level of significance or gets smaller
