The conclusion using a = 0.05 and a one-tailed Mann-Whitney U test with a null hypothesis of equal medians between two groups would be to retain the null hypothesis (H₀) if the calculated p-value is greater than 0.05. Without knowledge of the calculated p-value, we can only choose to retain or reject the null hypothesis based on the given alpha level of 0.05. Therefore, the best choice is to retain the null hypothesis (H₀).
