It is believed that 18% of Americans have allergies. A two year college student is thinking about going to medical school and is wondering if it is higher where he lives as he feels like he knows many people with allergies. He randomly selected 140 people from his contacts at his college. What is the probability of him getting a sample in which 20% or more of them have allergies if in fact 18% of Americans (as well as his contacts) have allergies?
