54 bodybuilders who used the anabolic steroid Anavar reported a mean gain in muscle mass of 8.3 lbs., with a standard deviation of 2.1 lbs. 31 bodybuilders who used the veterinary anabolic steroid Equipoise reported a mean gain in muscle mass of 5.9 lbs., with a standard deviation of 1.9 lbs. To a 3% level of significance, can it be asserted that, in general, Anavar-using bodybuilders gain more muscle mass than do Equipoise-using bodybuilders?
