A recent study cоmpаred the results оf twо weight loss drugs, Drug A аnd Drug B. A rаndom sample was obtained of 100 unrelated individuals; 50 of them were randomly assigned to take Drug A, and the other 50 took drug B. The number of pounds lost by each patient under the drug was recorded. The study wanted to see if one weight loss drug was more effective than the other. The summary statistics for the study are shown in the table below (note: not all information in the table is required to solve the problem; you must decide what pieces of information are necessary). Group n x̄ s Drug A 50 12.3 2.9 Drug B 50 9.7 2.1 Differences 50 2.6 1.0 Assuming all conditions are met, what is the 95% confidence interval for the difference in average weight lost between the two drugs? (difference = Drug A Weight Loss - Drug B Weight Loss).
