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 608 employed persons and 719 unemployed persons are independently and randomly selected, and that 318 of the employed persons and 269 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=0.01 for the test.

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
