A Two-Way ANOVA Summary Table is shown below. Source SS d.f. MS F Factor A 16.63 2 2.57 4.89 Factor B 5.13 2 2.57 1.51 Interaction A B 17.88 4 4.47 2.63 Within (error) 61.20 36 1.7 Total 100.844 44

The critical value for the F test using a= 0.05, d.f.N. = 2, and d.f.D = 36 is 3.26. Then, options:

only the null hypothesis concerning Factor A should be rejected.

only the null hypothesis concerning Factor B should be rejected.

only the null hypothesis concerning Factor A and the Interaction (AB) effect should be rejected.

all of the null hypotheses should be accepted.
