7) Answer the questions below for hypothesis A and B.
1.What is the test statistic? (Round to two decimal places as needed.)
2. What are the critical values? (Round to three decimal places as needed.)
3. Since the test statistic (falls/does not fall) in the rejection region, (reject/do not reject) Ho. There is (sufficient/ not sufficient) evidence to conclude that the mean of population 1 is different from population 2.
4.What is the P value?
5. Since the p-value is (greater then/less then) a, (reject, do not reject) Ho. There is (sufficient/ not sufficient) evidence to conclude that the mean of population 1 is different from population 2.
