If the test statistic equals the rejection region, do we make a decision that we reject the Ho?  So if we reject Ho, what is our conclusion??  there is sufficient evidence that we believe the Ha... the mean survival period is greater than 15.85 years?  Thank you.

Use the following information to answer questions 3, 4, 5 and 6 It is generally agreed that a certain standard treatment yields a mean survival period =|5,85 of 15.85 years for cancer patients.
