Similarity binomial distribution.
The variance of of a binomial distribution is similarly evaluated by combin- ing Equations (1.11) and (2.4): (x - u) n! x!(n - x)! p*(1 - p)"-x = np(1 - p) (2.7)essemen Countdown: Days:-6 Time:-15:36:45 A. 0 0.019 B. 0 0.19 C. 0 -0.019 D.

In 2014, students in an advanced Statistics course at UC Berkeley conducted an anonymous survey about use of cognition-enhancing drugs among college to points males. One survey group of males included members from a fraternity, and the other survey of males group 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 p, = 0.32, m = 131, py = 0.23, n2 = 94.
