**Critical region and critical values BrainMass**

When testing for significance, you are testing your data to see if your value falls in the critical region, defined as the statistical value that will allow you to reject the null hypothesis.... Probability Theory and Mathematical Statistics. Home. Lesson 55: Best Critical Regions. Printer-friendly version . In this lesson, and the next, we focus our attention on the theoretical properties of the hypothesis tests that we've learned how to conduct for various population parameters, such as the mean ? and the proportion p. Specifically, in this lesson, we will investigate how we know

**PinkMonkey.com Statistics Study Guide 8.7 Critical Region**

The critical region of the sampling distribution of a statistic is also known as the ? region. It is the area, or areas, of the sampling distribution of a statistic that will lead to the rejection of the hypothesis tested when that hypothesis is true.... The observation values in the population beyond the critical value are often called the “critical region” or the “region of rejection“. Critical Value: A value appearing in tables for specified statistical tests indicating at what computed value the null hypothesis can be rejected (the computed statistic falls in the rejection region).

**Hypothesis Testing Academic Skills Kit (ASK) - Newcastle**

Critical Region A critical region , also known as the rejection region, is a set of values for the test statistic for which the null hypothesis is rejected. i.e. if the observed test statistic is in the critical region then we reject the null hypothesis and accept the alternative hypothesis.... How to Graph the Two-Tailed Critical Region for a Significance Level of 0.05 To create a graphical equivalent to a 1-sample t-test, we’ll need to graph the t-distribution using the …

Get this critical value with the EQUATION SOLVER, just like we did for the first problem. We now see that . The test statistic falls into the rejection region, i.e., 11.302 > 9.210, therefore we reject H 0 .

## How To Find Critical Region Statistics

### Critical Region A critical region , also known as the rejection region, is a set of values for the test statistic for which the null hypothesis is rejected. i.e. if the observed test statistic is in the critical region then we reject the null hypothesis and accept the alternative hypothesis.

- The critical region CR, or rejection region RR, is a set of values of the test statistic for which the null hypothesis is rejected in a hypothesis test. That is, the sample space for the test statistic is partitioned into two regions; one region (the critical region) will lead us to reject the null hypothesis H 0 , …
- The following solution explains how to determine the critical region and critical values for z that would be used to test the null hypothesis at the given level of significance.
- The critical region of the sampling distribution of a statistic is also known as the ? region. It is the area, or areas, of the sampling distribution of a statistic that will lead to the rejection of the hypothesis tested when that hypothesis is true.
- In statistics, we call these shaded areas the critical region for a two-tailed test. If the population mean is 260, we’d expect to obtain a sample mean that falls in the critical region 5% of the time. The critical region defines how far away our sample statistic must be from the null hypothesis value before we can say it is unusual enough to reject the null hypothesis.
