Quizplus · Accepted Answer

The critical value, which is used in hypothesis testing to determine whether or not to reject the null hypothesis, depends on the level of significance chosen and the degrees of freedom (which is related to the sample size). As the sample size increases, the degrees of freedom increase, and the critical value decreases. Therefore, choice A is the best answer.
