For an experiment involving 3 levels of factor A and 3 levels of factor B with a sample of n = 8 in each treatment condition,what are the df values for the F-ratio for the AxB interaction?
A)2, 63
B)4, 63
C)6, 63
D)8, 63

The degrees of freedom for the AxB interaction is calculated as (levels of A - 1) * (levels of B - 1). Here, (3-1)*(3-1) = 4. The total degrees of freedom is calculated as (total number of observations - number of groups), which is (3*3*8 - 9) = 63. Thus, the df for the AxB interaction is 4, 63.
