What is the region of rejection?
Region of Rejection.
For a hypothesis test, a researcher collects sample data.
If the statistic falls within a specified range of values, the researcher rejects the null hypothesis .
The range of values that leads the researcher to reject the null hypothesis is called the region of rejection.
How do I find my acceptance region?
How to Find the Region of Acceptance
- Estimate population variance.
- Compute standard error.
- Choose a significance level.
- Find the critical value.
- Find the upper limit (UL) of the region of acceptance.
- In a similar way, we find the lower limit (LL) of the range of acceptance.
Is Alpha the rejection region?
The rejection region is chosen so that the probability is α that it will contain the test statistic when the null hypothesis is true, thereby leading to a Type I error. The value of α is usually chosen to be small (e.g, 0.01, 0.05, or 0.10) and is referred to as the level of significance of the test.
