Using a right tail test and alpha = 0.05 the critical t is: 2.13. Since the test statistic (1.98) lies to the left of the critical t (2.13), we fail to reject the null hypothesis that the difference between pre-test score and post-test score is zero..If the test statistic lies in the critical region, reject the null hypothesis in favor of the alternative hypothesis, if it does not, then you would fail to reject the hull hypothesis. To save time and effort the table below relates critical z values to alpha levels and type test.
