For a binomial probability distribution, n = 20 and p = .60.

a. Find the probability P(x 14) by using the table of binomial probabilities (Table I of Appendix C).

b. Find the probability P(x = 14) by using the normal distribution as an approximation to the binomial distribution. What is the difference between this approximation and the exact probability calculated in part a?
