How do you find the rejection region
WebUsing the rejection region approach, you need to check the table or software for the critical value every time you use a different α value. 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 » WebCritical 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 …

WebThe probability plot below displays the critical values and the rejection regions for a two-sided z-test with a significance level of 0.05. When the z-score is ≤ -1.96 or ≥ 1.96, it exceeds the cutoff, and your results are statistically significant. One-Sided Tests One-tailed tests have one rejection region and, hence, only one critical value. WebUsing the rejection region approach, you need to check the table or software for the critical value every time you use a different α value. In addition to just using it to reject or not …
