How To Find Rejection Region?

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.
