Question

Information for Questions 10 - 11: Although U.S. citizens value the freedoms and rights of democracy, they often do not vote. Data on x: the number of U.S. citizens eligible to vote (in millions) and y: the number of U.S. citizens who actually did vote (also in millions) in all the Presidential Elections since 1964 entered into MINITAB The following statistics were calculated: x-bar = 173.3 sx= 41.3 y-bar = 95.1 sy = 20.8 r = .958 Create the regression equation for X: Voting Age Population (in millions) and Y: Voter Turnout (in millions). Here are the formulas you need to find the slope and y-intercept for the linear regression equation. Round each value (slope and y-intercept) to the nearest thousandth: slope = r(sy/sx) y-intercept = y-bar - slope * x-bar

Use your regression equation in Question#10 to predict the turnout in the upcoming presidential election (2020) at which time the voting age population is estimated at 255 million.

a. 236 million b. 244.8 million c. 130 million d. 134.5 million e. 123 million
