Which one of the following statements is correct? A. D = 20 and k = 4 and the upper 5% critical value for this problem is 3.29. maxs? = 2.4 have an F20; 20 distribution. B. U = mins c. JMP does not give the U- test of our study guide, and it does not provide appropriate alter- native tests to test for Ho : of = 0} = o} = oị. D. The hypothesis are Họ : o} = o} = 0} = 0ž against H : o; = o; for all p and q.
