The Normal Approximation to the  Binomial Distribution A normal distribution is often used to solve problems  that involve the binomial distribution since when  is  large (say, 100), the calculations are too difficult to do  by hand using the binomial distribution. 2
Binomial Distribution The normal approximation to the binomial is  appropriate when  np > 5 and  nq > 5 In addition, a  correction for continuity  may be  used in the normal approximation to the binomial. The continuity correction means that for any  specific value of  X , say 8, the boundaries of  in  the binomial distribution (in this case, 7.5 to 8.5)  must be used. 3
