Suppose we had a genetic experiment where we hypothesize the 9:3:3:1 ratio of characteristics A, B, C, D. The hypotheses to be tested are H0: p1 = 9/16, p2 = 3/16, p3 =3/16, p4 =1/16, H1: at least two proportions differ from those specified. A sample of 160 offspring are observed and the actual frequencies are 82, 35, 29, and 14, respectively.
