A)Reject the null hypothesis with a = .05 but not with a = .01.
B)Reject the null hypothesis with either a = .05 or a = .01.
C)Fail to reject the null hypothesis with either a = .05 or a= .01.
D)There is not enough information to determine the correct decision.

A)​Reject the null hypothesis with a = .05 but not with a = .01.
B)​Reject the null hypothesis with either a = .05 or a = .01.
C)​Fail to reject the null hypothesis with either a = .05 or a= .01.
D)​There is not enough information to determine the correct decision.

Since the F-ratio is significant at a = .05 but not at a = .01, we can conclude that we should reject the null hypothesis at a = .05 but not at a = .01. Therefore, the correct statistical decision is to reject the null hypothesis with a = .05 but not with a = .01.
