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

question 165

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 $\mu _ { \mathrm { d } }$ , the mean value of the differences d for a population of paired data, is different from 0 . Given a sample of $n = 23$ and a significance level of $\alpha = 0.05$ , what criterion would be used for rejecting the null hypothesis?

• A) Reject null hypothesis if test statistic \(> 2.069\) or \(< - 2.069\).
• B) Reject null hypothesis if test statistic \(> 2.074\) or \(< - 2.074\).
• C) Reject null hypothesis if test statistic \(> 1.717\).
• D) Reject null hypothesis if test statistic \(> 1.717\) or \(< - 1.717\).
