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

question 31

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 $\alpha = 0.01$ 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 >2.602 .
• C) Reject null hypothesis if test statistic >2.624 .
• D) Reject null hypothesis if test statistic >2.977 or <-2.977 .
