WebIn hypothesis testing usually a significance test is performed and the rejection region is given in the form of a statistic such as a t score or a z score. It can just as easily be given in terms of the actual (non-standardized) parameter value.

WebRejection region definition, the set of values of a test statistic for which the null hypothesis is rejected. See more. 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.
