Answer to Question 1

D
The alternative hypothesis states that there is a difference (unequal means) between the groups that is caused by the manipulation of the independent variable.

Answer to Question 2

D
To say that the group means are equal is to say that they are NOT different. That says the same thing as the null hypothesis.
