WebIn hypothesis testing, there are two ways to determine whether there is enough evidence from the sample to reject H 0 or to fail to reject H 0. The most common way is to compare the p-value with a pre-specified value of α, where α … WebRejection region is in the negative section of the z (standard normal) distribution. You compute the z score and it is 3.00, clearly in the right tail in the exterme region. Again, …

Definition of Rejection Region For Chi Square Test Chegg.com

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 » You, as a researcher, choose the alpha level you are willing to accept. For example, if you wanted to be 95% confident that your results are significant, you would choose a 5% alpha level (100% – 95%). That 5% level is the rejection region. For a one tailed test, the 5% would be in one tail.
