Researchers recently conducted a study to determine whether the medication Paxil is effective in the treatment of depression.  Depression was measured using the Hamilton depression scale with the results below. Placebo Group:  Sample mean = 22.97, sample standard deviation = 3.55, n = 40 Paxil Treatment Group:  Sample mean - 19.91, sample standard deviation = 3.40, n = 40 Find the 95% confidence interval estimate for the difference between the two means. Specify which group you are using as group 1 and which group you are using as group 2. Identify the critical t-score for your margin of error.

Question

Researchers recently conducted a study to determine whether the medication Paxil is effective in the treatment of depression.  Depression was measured using the Hamilton depression scale with the results below.

Placebo Group:  Sample mean = 22.97, sample standard deviation = 3.55, n = 40

Paxil Treatment Group:  Sample mean - 19.91, sample standard deviation = 3.40, n = 40

Find the 95% confidence interval estimate for the difference between the two means.

Specify which group you are using as group 1 and which group you are using as group 2.

Identify the critical t-score for your margin of error.
