Answer to Question 1

One may use the normal distribution to approximate the binomial distribution, provided that both np  5 and nq  5. You would choose to approximate by the normal distribution if a computer and software were not available, if the table did not contain the required values of n and p, or if the computations could not be easily and expediently done with the binomial probability formula.

Answer to Question 2

A
