The com- puted independent t test statistic is .741, and the critical value is 2.201. Because the computed value does not exceed the critical value, it can be concluded that no statistically significant difference exists between the two groups. Also, in SPSS, the p-value for the t test is .474. Thus, the conclusion is that people who took the
