A researcher obtains t = 2.35 for a repeated-measures study using a sample of n = 8 participants.Based on this t value,what is the correct decision for a two-tailed test?
A)Reject the null hypothesis with 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)Change α to α = .10.

Without more information about the specific hypothesis being tested and the degrees of freedom, we cannot calculate the exact p-value associated with a t-value of 2.35. However, we know that the t-value is not large enough to reject the null hypothesis at either the alpha = .05 or alpha = .01 level. Therefore, the correct decision is to fail to reject the null hypothesis with either alpha level. Choice A and B are incorrect because they suggest rejecting the null hypothesis, which is not supported by the t-value provided. Choice D is incorrect because changing the alpha level to .10 would increase the likelihood of falsely rejecting the null hypothesis.
