Question: Anorexia. Hearing anecdotal reports that some patients undergoing treatment for the eating disorder anorexia seemed to be responding positively to the antidepressant Prozac, medical researchers conducted an experiment to investigate. They found 93 women being treated for anorexia who volunteered to participate. For one year, 49 randomly selected patients were treated with Prozac and the other 44 were given an inert substance called a placebo. At the end of the year, patients were diagnosed as healthy or relapsed, as summarized in the table:
Prozac Placebo Total
Healthy 35 32 67
Replace 14 12 26
Total 49 44 93
Do these results provide evidence that Prozac might be helpful in treating anorexia? Explain.
