(A) Why can the normal distribution be used as an approximation to the binomial distribution?
As n approaches infinity the binomial distribution approaches a normal dist.
-----------------
(B) What conditions must be met in order to use the normal distribution to approximate the binomial distribution?
np and nq must be >=5
-----------------
(C) How does the standard normal distribution differ from the normal distribution
The standard has mean at zero and std = 1
