The following values of Fobs occurred in a two-factor between-subjects analysis of variance: F(1, 28) for factor A = 3.47, F(1, 28) for factor B = 4.29, and F(1, 28) for the interaction of factors A and B = 4.10. Fcrit(1, 28) = 4.20 for alpha = .05. In this experiment you would H0 for factor A, H0 for factor B, and H0 for the interaction of factors A and B.
A)reject; reject; reject
B)fail to reject; fail to reject; fail to reject
C)fail to reject; reject; fail to reject
D)reject; fail to reject; reject

For factor A, Fobs (3.47) is less than Fcrit (4.20), so we fail to reject H0. 
For factor B, Fobs (4.29) is greater than Fcrit (4.20), so we reject H0. 
For the interaction of A and B, Fobs (4.10) is less than Fcrit (4.20), so we fail to reject H0. Therefore, the best choice is C because we fail to reject H0 for factor A and the interaction of A and B, but reject H0 for factor B.
