The Federal Election Commission maintains data showing the voting age population, the number of registered voters, and the turnout for special electons. The following table shows the voter turnout as a percentage of the voting age population in presidential elections from 1964-2000:

Year        % Vote             Year          % Vote             Year            % Vote

1964       61.92                1980        52.56                  1996          49.08

1968       60.84                1984        53.11                  2000          51.30

1972       55.21                1988        50.11

1976      53.55                 1992        55.09

4: Use your equation to forecast the percent of voters in 2004. Round to nearest whole number.

Include units in your answer.

Solution

The general linear trend equation is   Y = b₀ + b₁ X

where b₀ = intercept

and X = slope

Y = 60.55 - 1.14 X

Forecast for the percent of voters in 2004 = 60.55 - 1.14 * 11

Forecast for the percent of voters in 2004 = 48 %
