Question 1180120
A. The null hypothesis is either true or not, so that doesn't change.
B. It becomes EASIER to reject Ho, so not B, but C.
C. Yes
D. It becomes EASIER to reject Ho, so D can't be correct. 
E. Is correct, although the wording should say something about rejecting the null, ideally. We don't really prove the null hypothesis is true or false; we reject it to fail to reject it are better terms. I'm not sure how much of a stickler the teacher is for words. It becomes more difficult to accept Ho.
F. Is true
G. is not.
