T test critical value rejection region
WebRejection region/Signi cance: P(x in rejection region jH 0) = . The p-value is a tool to check if the test statistic is in the rejection region. It is also ameasure of the evidence for rejecting H 0. p-value: P(data at least as extreme as x jH 0) \Data at least as extreme" is de ned by the sidedness of the rejection region. April 14, 2024 4 / 26 WebIf the value of T computed in the sample lies in the rejection region, that is, if T is greater than or equal to the upper critical value or if T is less than or equal to the lower critical value, the null hypothesis H 0 must be rejected in favor of the alternative hypothesis H 1.Otherwise, the null hypothesis H 0 cannot be rejected.. The following figure illustrates the …
