Assume that n is odd and that all m elements of the first sample are below the median of the second sample. Find the range of the test statistics and the rejection region for the appropriate alternative hypothesis using: (i) The Wilcoxon test. (ii)

The Mann–Whitney test. (iii) The runs test. (iv) The Kolmogorov–Smirnov test for the appropriate alternative hypothesis. (α = 0.05, n = 51, m = 20)
