Please see attached file for full question and ANOVA table.
1. For each of the following situations, state how large the F statistic needs to be for rejection of the null hypothesis at the 5% level. Sketch each distribution and indicate the region where you would reject.
a). The main effect for the first factor in a 3 x 5 ANOVA with 3 observations per cell.
b). The interaction in a 3 x 3 ANOVA with 3 observations per cell.
c). The interaction in a 2 x 2 ANOVA with 51 observations per cell.
This solution shows how to find the degrees of freedom and critical values of F in an ANOVA table involving 2 factors.
