Researchers compared an experimental drug with the standard drug for the treatment of a certain disease, 300 were given the experimental drug and 500 were given the standard drug. The number of patients who recovered from each group were recorded as follows Experimental Drug Standard drug Number of patients in Total 300 500 Number of recovered patients 225 371 Can we conclude, at the 10% level of significane, that the experimental drug had a higher proporion of recovered patients than the standard drug?1. 2. 3 S = 71-1 4 D = 5. 6 N-1 M-1 N-1 7 C.V.= or 8.
