X² = 4.81.
What is the appropriate statistical decision for this outcome?

α = .05 but not with
α = .01.
b. Reject the null hypothesis with either
α = .05 or
α = .01.
c. Fail to reject the null hypothesis with either
α = .05 or
α = .01.
d. There is not enough information to determine the appropriate decision.
