Question
Is drinking strong coffee more efficient in lowering blood alcohol content (BAC) than simply waiting after alcohol consumption? We should take into consideration that body fat content differs substantially between men and women overall, affecting how alcohol is absorbed and metabolized. Thirty subjects, 18 men and 12 women, agree to drink alcohol until their BAC reaches 0.08. The treatment is applied at that point, and the BAC is measured two hours later.
Match the following experimental designs to the description of their set-up.
Randomly assign 15 of the subjects to drink strong coffee while the other 15 subjects simply wait. a. Randomized block design On two separate days, all 30 subjects will drink to BAC 0.08. Randomly assign 15 of the subjects to the coffee group on the first day and wait on the second. The other 15 subjects wait on the first day and drink coffe on the second. b. Completely randomized design Randomly assign 6 of the women and 9 of the men to drink strong coffee while the remaining subjects simply wait. c. Matched pairs designExplanation / Answer
