 Suppose you wish to test the claim that μd, the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n=15 and a significance level of α=0.01, what decision criterion would be used for rejecting the null hypothesis?
A. Reject the null hypothesis if the computed test statistic is ≤2.624.
B. Reject the null hypothesis if the computed test statistic is ≥2.602.
C. Reject the null hypothesis if the computed test statistic is ≥2.624.
D. Reject the null hypothesis if the computed test statistic is ≥2.977 or ≤ -2.977.
