A city counsel is trying to decide to levy an additional gas tax to help with city improvements. A random sample of
400 voters in the city are asked if they favor an additional 4% gasoline sales tax to provide badly needed revenues for
street repairs. The counsel has decided it will implement the tax if at least 60% of the voters favor the tax. The
survey finds 220 out of the 400 favor the tax. Should the counsel proceed?
