Time magazine reported the result of a telephone poll of 800 adult Americans. The question posed of the Americans who were surveyed was: "Should the federal tax on cigarettes be raised to pay for health care reform?" The results of the survey were: Non-smoker Smoker N₂ = 195 N₁ = 605 Y₁ = 351 said yes Y₂ = 41 said yes Is there sufficient evidence at the a = 0.05 level, to conclude that the two populations (smokers and non-smokers) is differ significantly with respect to their opinions?
