statistics - Hypothesis testing: finding the rejection region …

WebThe rejection region corresponds to the alternative hypothesis. The graph would look like this To reject the null, the tail used for the rejection region should cover the extreme values of the alternative hypothesis - the area in red. The z or t score is negative and less than the score set for the rejection condition. WebI can come up with two different ways to determine the rejection region: { T ( x) − μ > c }. μ is the mean of the distribution F of T ( X) under null, and c is determined by solving inf c ≥ 0 c subject to P T ( X) ∼ F ( T ( X) − μ > c) ≤ α. So the rejection region is symmetric around μ. 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 » small flower pokemon
