Answer to Question 1

D
The F ratio for the repeated measures factor (B) is the mean square of Factor B divided by the mean square of the interaction of Factor B and subject within groups.

Answer to Question 2

B
The degrees of freedom associated with the subject within group error term equals a(n-1), where a equals the number of levels of the between subjects factor, and n equals the number of persons in each level of the between subjects factor.
