Given a Binomial Distribution with N Trials and Probability P $n p \geq 5$

question 32

Multiple Choice

Given a binomial distribution with n trials and probability p of a success on any trial, a conventional rule of thumb is that the normal distribution will provide an adequate approximation of the binomial distribution if:

• A) \(n p \geq 5\) and \(n ( 1 - p ) \geq 5\).
• B) \(n p \leq 5\) and \(n ( 1 - p ) \leq 5\).
• C) \(n p \geq 5\) and \(n ( 1 - p ) \leq 5\).
• D) \(n p \leq 5\) and \(n ( 1 - p ) \geq 5\).
