D)the mean and standard deviation

Question

Quizplus · Accepted Answer

The correspondence between binomial and normal distributions depends on the values of n and p. Specifically, if n is large (usually considered to be above 30) and both np and n(1-p) are greater than or equal to 5, then the binomial distribution can be approximated by the normal distribution. This approximation is known as the normal approximation to the binomial distribution. Therefore, the best choice for the values that determine the correspondence between the binomial and normal distributions is n and p.
