Unformatted text preview: 3. (a) MSE 2 9659, J i 12 for all i . There are 7 comparisons to be made. Now t 88 025 7 2 754, so the 5% critical value is 2 754 2 9659 1 12 1 12 1 936. All the sample means of the noncontrol formulations differ from the sample mean of the control formulation by more than this amount. Therefore we conclude at the 5% level that all the noncontrol formulations differ from the control formulation. (b) There are 7 comparisons to be made. We should use the Studentized range value q 7 88 05 . This value is not in the table, so we will use q 7 60 05 4 31, which is only slightly larger. The 5% critical value is 4 31 2 9659 12 2 14. All of the noncontrol formulations differ from the sample mean of the control formulation by more than this amount. Therefore we conclude at the 5% level that all the noncontrol formulations differ from the control formulation....
