A therapist wishes to show that his new therapy is a marked improvement over the current best available therapy. To do so he examines the number of participants who improved with each. A total of 125 participants received his treatment (and 100 of them improved). A total of 80 participants received the alternative treatment (and 64 of them improved). What should the therapist conclude?

AHis treatment is superior to the alternative because 100 is greater than 64

BHis treatment is no better than the alternative because the percentages are the same

CHis treatment is inferior because the percentages are the same

DHis treatment is superior because it included 125 people as opposed to 80
