Question: Using Table E.6, determine the lower- and upper-tail critical values for the Wilcoxon rank sum test statistic, T 1 , in each of the following

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. a = 0.10, n1 = 6, n2 = 8 b. a

d. Given the results in (a) through (c), what do you conclude regarding the width of the region of nonrejection as the selected level of significance, a, gets smaller?

= 0.05, n = c. a = 0.01, n, = %3D 6,

a. a = 0.10, n1 = 6, n2 = 8 b. a = 0.05, n = c. a = 0.01, n, = %3D 6, n = 8 6, n = 8 %3D
