A Gallup survey asks a random sample of American adults this question. “In this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?” The responses are 1 = satisfied, 2 = dissatisfied. The survey results from this year and one 5 years ago were recorded. Is there enough statistical evidence to infer that American adults are less satisfied with the freedom to choose what do to with their lives than they were 5 years ago?
