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) np ≤ 5 and n(1 − p) ≤ 5
B) np ≥ 5 and np(1 − p) ≥ 5
C) np ≥ 5 and n(1 − p) ≥ 5
D) None of these choices.

Binomial Distribution

A probability distribution that summarizes the likelihood that a value will take one of two independent states under a given number of observations.

Normal Distribution

A bell-shaped frequency distribution curve that is symmetrical about the mean, representing the distribution of many types of data.

  • Identify conditions under which the normal distribution can be used as an approximation for the binomial distribution.
