Suppose that we wish to study the effect of computer-aided instruction (CAI) onthe performance of college students. We randomly divide the incoming class intothree sections. Section A is taught in a conventional way, Section B is (nearly)completely automated, and in Section C a mixed approach is used. The followingtest scores are observed:Section A Section B Section C77 70 7968 69 7472 73 7775 74 8060 59 7359 63 6082 80 79Perform an analysis of variance and determine whether the differences amongthe means obtained for the three sections are significant at = 0.05.
