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 = .03 c. n = 10, p = .6 e. n = 200, p = .02 b. n=100, p = .04 d. n = 500, p = .05 f. n = 35, p = .3
