In 2014, students in an advanced Statistics course at UC Berkeley conducted an anonymous survey about use of cognition-enhancing drugs among college males. One survey group of males included members from a fraternity, and the other survey group of males included no fraternity members. The standard error formula for the difference between sample proportions is Calculate the standard error for a survey comparing proportions of cognition- enhancing drug use of fraternity members to non-fraternity members, where p1 - 0.34, n1 = 139, p2 = 0.25, n2 = 94. Round all calculations to the thousandth decimal place. 0.404 0.059 0.062 0.060
