Question 3.8

This graph shows another experimental design that does not include a placebo. What could one conclude about the analgesic efficacy of Drug X?

Treatments were drug X, morphine 12 mg, and morphine 6 mg. Drug X and morphine 12 mg provided a large amount of relief, similar to each other and statistically greater than did morphine 6 mg.

Selection ADrug X is effective, as shown by its superiority to morphine, 6 mg.
Selection BThe result is inconclusive, as there is no evidence of assay sensitivity.
