10.1 Generate by enumeration the exact null distribution of the k-sample median test statistic for k ¼ 3, n1 ¼ 2, n2 ¼ 1, n3 ¼ 1. If the rejection region consists of those arrangements which are least likely under the null hypothesis, find this region R and the exact

a. Compute the values of the Q statistic for all arrangements and compare that critical region for the same value of a with the region R.
