Determine the Decision Criterion for Rejecting the Null Hypothesis in the Given

Multiple Choice

Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. Suppose you wish to test the
Claim that $\mu _ { d }$ , 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 $\alpha = 0.01$ 1, what criterion would be used for rejecting the null
Hypothesis?

A) Reject null hypothesis if test statistic > 2.624.
B) Reject null hypothesis if test statistic < 2.624.
C) Reject null hypothesis if test statistic > 2.602.
D) Reject null hypothesis if test statistic > 2.977 or < -2.977.
