Question

Quizplus · Accepted Answer

This portion of the sampling distribution is called the region of rejection, as it is rejecting the null hypothesis. This region is determined by a critical value, which is the point beyond which values are too unlikely to have occurred by chance. Therefore, option C (Region of rejection) is the correct choice. Option A (Region of criterion value) is not a commonly used phrase in statistics, while option B (Region of critical value) is a similar concept but not specific to rejecting a null hypothesis. Option D (Critical value) is only a part of the region of rejection but is not exclusive to it.
