Answer to Question 1

D
The degrees of freedom between will be represented in the table as degrees of freedom in the numerator. The degrees of freedom within will be represented in the table as the degrees of freedom in the denominator. There will be multiple critical F values, each for a different level of alpha; therefore alpha must be known so that the correct critical value of F is reported.

Answer to Question 2

A
The sums of squares must be calculated before the mean squares or F ratios can be calculated. Q values are only calculated if F is significant.
