A hypothesis test is conducted to test the null hypothesis that the mean is less than 12. Use a 0.01 level of significance. What type of test is this? Right tail Two tail Left tail What is the critical value? 2.33 -2.33 1.78 correct answer is not given Suppose the test statistic was -2.50 What is the conclusion? Fail to reject Ho. There is not sufficent evidence to support the claim that the mean is less than 12. Reject Ho....
