WebIf the test statistic is more extreme in the direction of the alternative than the critical value, reject the null hypothesis in favor of the alternative hypothesis. If the test statistic is less extreme than the critical value, do not reject the … WebHowever, using the p-value approach has the following advantages: Using 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 ...

WebSep 13, 2024 · The p-value (or the observed level of significance) is the smallest level of significance at which you can reject the null hypothesis, assuming the null hypothesis is true. You can also think about the p-value as the total area of the region of rejection. Remember that in a one-tailed test, the regi WebBecause there are two rejection regions, we must split our significance level in half. Each rejection region has a probability of α / 2, making the total likelihood for both areas … WebTo determine the critical region for a normal distribution, we use the table for the standard normal distribution.
