If a hypothesis test produces a zscore in the critical regio

If a hypothesis test produces a z-score in the critical region, what decision should be made?

Solution

Rejection region approach used in Hypothesis Testing:

If the hypothesis produces a z score that falls in the critical region, then we reject the null hypothesis H0.

If the hypothesis doesnot produces a z score that falls in the critical region, then we \'do not reject the null hypothesis H0.
