Making Decision

Lastly a decision  should  be arrived as to whether the null  hypothesis is  to be accepted  or rejected. In  this regard the value  of the test  statistic computed to test the  hypothesis plays  a very important role. If the  computed value of the test  statistic is less than  the  critical  value the computed value of the test statistic falls in the acceptance region and  null  hypothesis is accepted. If the computed value of the test  statistic  is greater than  the critical  value the  computed value of  the test statistic fall in the rejection region  and null hypothesis  is rejected. Usually  5% level of significance α = 0.05 is used  in testing  a hypothesis  and  taking a decision unless otherwise  any other level of significance is specifically stated.
