A group of physiotherapists has come up with a new method to treat ankle injuries. To test its effectiveness, they apply the traditional treatment to half of their patients (randomly selected) with ankle injuries and the experimental method to the other half. The efficiency of the methods is measured by the time (in days) taken to achieve complete recovery. The results are stored in the file Ankle. Is there evidence of a difference in the median performance between the two methods? (Use \(\alpha=0.05\).)
