Find rejection region
A rejection region (also called a critical region) is an area of a graph where you would reject the null hypothesis if your test results fall into that area. In other words, if your results fall into that area then they are statistically significant. Watch the video for an overview: What is a Rejection Region?

For example, if your statement asks “Is the average growth rate greater … See more There are two ways you can test a hypothesis: with a p-value and with a critical value. P-value method: When you run a hypothesis test (for example, a z test), the result of that test will be a p value. The p value is … See more You, as a researcher, choose the alpha level you are willing to accept.

In addition to just using it to reject or not reject H 0 by comparing p-value to α value, the p-value also gives us some idea of the strength of the evidence against H 0. « Previous.

WebA rejection region (or a critical region) is the region (denoted by RR) that specifies the values of the observed TS for which the null hypothesis will be rejected. From: … WebWhen the rejection region is taken on both ends of the sampling distribution, the test is called a two-sided test or two-tailed test. When we are using a two-sided test, half of the rejection region equal to α / 2 is taken on the right side and the other half equal to α / 2 is taken on the left side of the sampling distribution.
