You want to compare the effects of two different cold medicines on reaction time.

Suppose you measure the decrease in reaction times for one group of participants who take one capsule of drug A, and you do the same for a different group of participants who take drug B. The results are A: 1.96,2.24,1.71,2.41,1.62,1.93 B: 2.11,2.43,2.07,2.71,2.50,2.84,2.88.

Compare these two groups with the Wilcoxon-Mann-Whitney test using

α = .05. What is your estimate of the probability that a randomly sampled subject receiving drug A will have less of a reduction in reaction time than a randomly sampled subject receiving drug B?
