If possible please show me in detail.

b. The MINITAB ANO VA printout is shown here. Test for interaction at the a = 0.05 level of significance. Analysis of variance for response. c. Does the result warrant tests of the two factor mean effects?

Solution

b. The F-ratio for the interaction effect, as in the table, is given to be 1.48678. The degrees of freedom is (2,6).

From the tables, the critical value is found to be 5.14. Since F < F critical, the interaction is not significant.

Alternatively, p-value is found to be 0.30, which is > alpha. Hence, the interaction is not significant.

c. Yes, the result holds for 2 factor mean effect.
