Question

Quizplus · Accepted Answer

The standard deviation of a binomial random variable is the square root of npq, where n is the number of trials, p is the probability of success on a single trial, and q is the probability of failure on a single trial (q = 1 - p). The statement that the standard deviation is the square root of the mean is incorrect.
