6-6 Normal as Approximation to Binomial

Surprisingly, many discrete binomial probability distributions look approximately like continuous normal probability distributions. In those cases we can expand our application of the properties of normal distributions to binomial distributions.

Binomial Parameters
mean	μ = np
standard deviation	σ = √npq

The method for solving problems is very similar to those learned in chapter 6-3 and 6-5 except you have to use the binomial formulas to compute the mean and standard deviation before you compute z.
