Question: Using Table E.6, determine the lower- and upper-tail critical values for the Wilcoxon rank sum test statistic, T1, in each of the following two-tail tests:

Using Table E.6, 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. α = 0.10,n1 = 6, n2 = 8
b. α = 0.05,n1 = 6, n2 = 8
c. α = 0.01,n1 = 6, n2 = 8
d. Given your results in (a) through (c), what do you conclude regarding the width of the region of nonrejection as the selected level of significance, α, gets smaller?
