According to a study done by the Gallup organization, the proportion of Americans who are satisfied with the way things are going in their lives is 0.82. Suppose a random sample of 100 Americans is asked the question "Are you satisfied with the way things are going in your life?" What is the probability the proportion of people who answer yes exceeds 0.85? Would it be unusual for a survey of 100 Americans to reveal that 75 or fewer are satisfiedwith the way things are going in their life?
