Question

are the end of the treatment scores of depression different at a significant p value? How do you think this relates to 0 being in the interval for 95% CI for group differences in depression?

ct the confidence interval simply by adding e mean I just as we did in Section 8.2. "-1-5-1-4 Table 2.

Answer 1

The 95% confidence interval of the treatment scores of depression is between -4.8 and 1.0.

Since the confidence interval contains 0, we cannot conclude that there is a significant difference in the treatment scores of depression.
