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 » WebNov 15, 2024 · 1 Answer.

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.
