Question

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 649 employed persons and 666 unemployed persons are independently and randomly selected, and that 364 of the employed persons and 299 of the unemployed persons have registered to vote. Can we conclude that the percentage of employed workers ( p1 ), who have registered to vote, exceeds the percentage of unemployed workers ( p2 ), who have registered to vote? Use a significance level of α=0.05 for the test.

Step 3 of 6:

Compute the weighted estimate of p, p‾‾. Round your answer to three decimal places.

step 4:

Compute the value of the test statistic. Round your answer to two decimal places.

Step 5 of 6:

Determine the decision rule for rejecting the null hypothesis H0H0. Round the numerical portion of your answer to three decimal places.

Step 6 of 6:

Make the decision for the hypothesis test.
