Question: In a population of executives (population A), 35% say that when they fly they prefer a certain airline. In another population of executives (population B), 50% prefer this airline. What is the probability that a simple random sample of size 100 from each population would yield a difference \({{\hat{p}}_{B}}-{{\hat{p}}_{A}}\) of 0.30 or more?
