The U.S. Census Bureau conducts annual surveys to obtaininformation on the percentage of the voting-age population that isregistered to vote. Suppose that 686 employed persons and 669unemployed persons are independently and randomly selected, andthat 438 of the employed persons and 361 of the unemployed personshave registered to vote. Can we conclude that the percentage ofemployed workers ( p1 ), who have registered to vote, exceeds thepercentage of unemployed workers ( p2 ), who have registered tovote? Use a significance level of α=0.01 for the test.
