Let ^p =k/n, where k= the number of successes in the n Bernoulli trials, with E(^p)=π. Assume we drew a random sample of n = 81 form our population, and we observed ^p=.40. Test the null hypothesis H0: π=.30 vs. the alternative hypothesis HA: π > 0.30 at the a = .05 level. Use the z distribution. Do you accept or reject H0? Why do you say that?
