Answer to Question 1

C
T is obtained by adding all the scores. Because the scores added across the rows and down the columns of the totals summary table produce marginals, T is also the sum of the marginals.

Answer to Question 2

D
The critical value of F is determined by consulting the table under the degrees of freedom associated with the numerator and denominator of the F ratio. When the degrees of freedom are the same for all values of the calculated F,all values of the critical F will also be the same.
