E.
five steps in the hypothesis testing
1) State the null and alternate hypotheses
2) Select the appropriate test statistic and level of significance.
3) State the decision rules (critical value for the test-statistic is
determined by the level of significance)
4) Compute the appropriate test statistic and make the decision.
5) Interpret the decision.
.......
invT(.05, 24) = 1.711
.......
invT(.015,24) and invT(.985,24) (� 2.307)
.......
A. Sample A = 11; sample B = 13 NOT true
(11 + 13) - 2 = 22
