We can use the normal distribution to approximate the binomial distribution when:
A)the sample size is at least 30
B)np and nq are both less than 5
C)np and nq are both more than 5
D)nx is greater than 30

Quizplus · Accepted Answer

The normal distribution can be used to approximate the binomial distribution when both np and nq are greater than 5, where n is the number of trials, p is the probability of success, and q is the probability of failure (q = 1-p). This ensures the distribution is approximately symmetric and bell-shaped.
