WebAnswer. For this problem, we know p = 0.43 and n = 50. First, we should check our conditions for the sampling distribution of the sample proportion. n p = 50 ( 0.43) = 21.5 and n ( 1 − p) = 50 ( 1 − 0.43) = 28.5 - both are greater than 5. Since the conditions are satisfied, p ^ will have a sampling distribution that is approximately normal ...
