True/False questions Question 1 [12 marks] The following statements are true in a one-way layout model with & treatments and sample sizes m,-.., My : (a) If n = -.. = n; = n, then it requires (nk)!/ k!(m!)* ] rank assignments to determine the exact distribution of the Kruskal-Wallis test statistic H . (b) If k = 3 and 1 = 1, = n; =2, then the distribution of the Jonckheere-Terpstra test statistic J for ordered alternatives can be determined by 15 rank assignments. (c) If the Jonckheere-Terpstra test rejects the null hypothesis Ho : 71 = ...= 6, at the level o of significance, so will do the Kruskal-Wallis test
