Answer :
Step 1:
critical region
if the value of the test statistic falls inside the critical region, then the null hypothesis is rejected at the chosen significance level. if the value of the test statistic falls outside the critical region, then there is not enough evidence to reject the null hypothesis at the chosen significance level.
Step 2
Explanation: If a Null Hypothesis is accepted then the value of Test statistic lies in the Acceptance region. For a rejected Null Hypothesis the value lies in the Rejection region.
Step 3
The null hypothesis is rejected if the value of a test statistic lies in the:
Rejection region
Final answer
A. Rejection region
