For the binomial sample sizes and null-hypothesized values of p in each part, determine whether the sample

Question:

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 = 500, P0 = .05
b. n = 100, P0 = .99
c. n = 50, P0 = .2
d. n = 20, P0 = .2
e. n = 10, P0 = .4
