Despite the strong economy in 2018 and 2019, many Americans were feeling stress, worry, and anger. A Gallup survey asked a random sample of Americans 1 = years old and older if they felt stress the previous day. The responses are 1 = Yes and 0 = No. Is there sufficient evidence to conclude that there are more Americans aged 15 and older who experienced stress the previous day than Americans aged 15 and older who did not experience stress the previous day?
