In a random sample of 220 potential voters registered in the state of Maryland, 86 indicated that they planned to vote in the next general election. In an independently chosen, random sample of 287 potential voters registered in Illinois, 95 indicated that they planned to vote in the next general election. Can we of all conclude, at the 0.05 level of significance, that the proportion p₁ of all potential voters in Maryland who plan to vote differs from the proportion p potential voters in Illinois who plan to vote? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
