Assume that x is a binomial random variable with n and p as specified in parts a–f that follow. For which cases would it be appropriate to use a normal distribution to approximate the binomial distribution?

a. n = 80, p = 0.03

b. n = 100, p = 0.04

c. n = 10, p = 0.6

d. n = 500, p = .05

e. n = 200, p = 0.02

f. n = 35, p = 0.3
