WebJul 10, 2016 · How to decide on a rejection region, or a test statistic indexing a set of rejection regions, is a chapter or two of an introductory book on theoretical statistics. The … WebTo find a rejection region, work backwards from the level of significance (α) to a value of the test statistic (call it z ∗ ). Values of the test statistic that are farther from the hypothesized value of μ x (i.e., values of z where z ∗ is between μ x and z) will lead to rejection of the null hypothesis. That sounds alot like what a p-value is?

We would fail to reject the null hypothesis and conclude that there is no evidence in the data to suggest that the median is above 160 minutes. This test is called the Sign Test and S + is called the sign statistic. The Sign Test is also known as the Binomial Test.

WebThis set is called critical or rejection region. Usually, one-sided tests have one critical value and two-sided test have two critical values. The critical values are determined so that the probability that the test statistic has a value in the rejection region of the test when the null hypothesis is true equals the significance level (denoted ... led shirts customWebThe subset that is considered to be consistent with the null hypothesis is called the "acceptance region"; another subset is called the "rejection region" (or "critical region").
