What is the rejection region?
Understand the Problem
The question is asking about the concept of the rejection region in statistics, specifically in the context of hypothesis testing. The rejection region refers to the set of values for which the null hypothesis is not considered plausible, leading to its rejection in favor of an alternative hypothesis.
Answer
Range of values for rejecting the null hypothesis
The rejection region is the range of values for a test statistic that leads to the rejection of the null hypothesis.
Answer for screen readers
The rejection region is the range of values for a test statistic that leads to the rejection of the null hypothesis.
More Information
When a test statistic falls within the rejection region, the null hypothesis is considered statistically improbable, leading to its rejection in favor of the alternative hypothesis.
Tips
A common mistake is misidentifying the critical value, leading to incorrect conclusions about the null hypothesis. Always cross-check with the significance level.
