Researchers have created a prediction equation to predict a state’s average SAT score (Y’) using the percentage of HS seniors who take the SAT as their predictor variable (X). The prediction equation has a slope of -2.5 and a y-intercept of 510. Knowing that 30 percent of all high school seniors in Wisconsin take the SAT, you predict Wisconsin’s average SAT score to be ; if Wisconsin actually has an average SAT score of 460, you calculate a prediction error of .
