Answer to Question 1

A
In order to be significant, the calculated F must be equal to or greater than the critical F. If it is not, then chance is a likely explanation for the results.

Answer to Question 2

D
If the calculated value of F is smaller than the critical value of F, the experimenter must conclude that there are no significant differences between the means. Any differences observed are likely to be due to chance.
