Last updated: 7/7/2022

The sample size n, probability of success p, and probability of failure q are given for a binomial experiment. Decide whether you can use the normal distribution to approximate the random variable x. n = 20 p=0.63 q=0.37 Can the normal distribution be used to approximate the random variable x? A. Yes, because np 25 and nq 25. B. No, because nq <5. C. No, because np <5 and nq < 5. D. No, because np < 5.
