You ran a simple regression trying to predict distance using club head speed for a random sample of golfers. The graph shows the residuals plotted against the club head speed. The residuals are grouped into three categories What is wrong with the regression model? Residuals 20 15 10 5 . 0 Low Skil 20 40 60 80 100 120 140 Residual -5 Mid Skill 1 -10 A high skil - 15 -20 -25 -30 Club Speed (MPH) Nothing is wrong, the model accurately predicts distance for all skill levels. The predicted distance for the low skill golfers is usually too low and the predicted distance for the O The predicted distance for the low skill golfers is usually too high and the predicted distance for the
