In 2014, students in an advanced Statistics course at UC Berkeley conducted an anonymous survey about use of cognition-enhancing drugs among college 1o points males. One survey group of males included members from a fraternity, and the other survey of males group included no fraternity members. The difference between the proportion of fraternity members who have used cognition-enhancing drugs and the proportion of n members who have used cognition-enhancing drugs is equal to o.054. Which one of the following conclusions is true? on-fraternity A. Students who are not fraternity members use cognition-enhancing drugs at higher rates than fraternity members. B. One possibility is that the proportion of fraternity members who have used cognition- enhancing drugs is 0.295 and the proportion of non-fraternity members who have used cognition-enhancing drugs is o.241. C. Students could have discovered that the proportion of fraternity members who have used cognition-enhancing drugs is o.315 and the proportion of non-fraternity members who have used cognition-enhancing drugs is o.369.
