A magazine conducted a random sample of 800 Americans and asked, "Should the federal tax on cigarettes be increased?" In that sample 650 were non-tobacco users, and 480 of these people said the federal tax should be increased. As well, the remaining 150 were tobacco users, and 98 said the federal tax should be increased. Test the hypothesis that the proportion of non-tobacco users who support an increase on the federal tax on cigarettes is greater than the proportion of tobacco users who support the federal tax increase. Use .05 as the level of significance.
