The following ANOVA table shows the results of a two-way factorial experiment with interaction. (2x4)
Source df SS MS F p-value
A 1 65 65 4.48 0.042
B 3 408 136 9.38 0.0001
AB 3 101 33.67 2.32 0.094
Error 32 464 14.5
Total 39 1038
Since the interaction between the two factors A and B is not significant based on the p-value, we need to test for main effects. Using the additive model, what is the value of the F-test statistic needed to test for the main effect of Factor B? Assume a 0.05 level of significance.
