Question: When can the normal distribution be used as an approximation to the binomial distribution?
A ) n.p = 5, n.q = 5 B ) n.p ≤ 5, n.q ≤ 5 C ) n.p > 5, n.q < 5 D ) n.p ≥ 5, n.q ≥ 5
Steps to derive
1 The normal distribution can be used as an approximation to the binomial distribution only when n.p and n.q are both greater than or equal to 5. So, n.p ≥ 5 and n.q ≥ 5.
