WebFeb 9, 2024 · The rejection region is fixed beforehand. If the null hypothesis is true then some α % of the observations will be in the region. The p-value is not the same as this α %. The p-value is computed for each separate observation, and can be different for two observations that both fall inside the rejection region. WebIf the test statistic is more extreme than the critical value, then the null hypothesis is rejected in favor of the alternative hypothesis. If the test statistic is not as extreme as the critical value, then the null hypothesis is not rejected. WebThis critical Z-value (CV) defines the rejection region for the test.
