Answer to Question 1

B

Answer to Question 2

If the null hypothesis is true, we would expect the F-ratio to be 1 or very close to 1 . We expect this because the null hypothesis states that there are no differences between the conditions and this means that the between-groups variance should be about the same as the within-groups variance, thus leading to an F-ratio of about 1.
