For the binomial sample sizes and null-hypothesized values of p in each part, determine whether the sample size is large enough to use the normal approximation methodology presented in this section to conduct a test of the null hypothesis H0: p = p0.

a. n = 600, p0 = .06

b. n = 200, p0 = .99

c. n = 40, p0 = .3

d. n = 30, p0 = .2

e. n = 20, p0 = .4
