Question
Two independent groups of patients were given Drug X and Drug Y. The recovery times (in days) are as follows:
| Drug X | 8 | 10 | 9 | 7 | 11 |
| Drug Y | 6 | 7 | 5 | 8 | 6 |
(i) State the null and alternative hypotheses.
(ii) Explain why the Mann–Whitney U test is appropriate for this data.
(iii) Perform the test at the 5% level of significance and draw a conclusion.

The problem involves comparing the recovery times of two independent groups of patients treated with Drug X and Drug Y, and the objective is to determine whether there is a statistically significant difference between the two treatments using the Mann–Whitney U test, interpreted within the broader frameworks of classical and Bayesian inference. The null hypothesis in this context states that there is no difference between the distributions of recovery times for the two drugs. In other words, the probability that a randomly selected patient from Drug X has a longer recovery time than a randomly selected patient from Drug Y is equal to the probability of the reverse. Symbolically, this can be expressed as (H_0: F_X = F_Y), where (F_X) and (F_Y) denote the distributions of recovery times for Drug X and Drug Y respectively. The alternative hypothesis states that the two distributions are not equal, implying that one drug tends to produce systematically shorter _____ ________ ________ ___ ____ __________ ______.
