The U.S. Census Bureau conducts annual surveys to obtain information on the percentage of the voting-age population that is registered to vote. Suppose that 679679 employed persons and 690690 unemployed persons are independently and randomly selected, and that 429429 of the employed persons and 369369 of the unemployed persons have registered to vote. Can we conclude that the percentage of employed workers ( p1p1 ), who have registered to vote, exceeds the percentage of unemployed workers ( p2p2 ), who have registered to vote? Use a significance level of α=0.05α=0.05 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test.
