The scаtter plоt belоw shоws а lineаr model of the relationship between two variables (red line). Five observations are highlighted and labeled A through E. For each observation, a blue point on the linear model illustrates the predicted value of the dependent variable, given the observed value of the independent variable. A dashed line connects the observation (solid black circle) to the prediction (solid blue circle), illustrating the direction and magnitude of the residual value. Use these plots to answer the questions that follow. Which data point has the smallest negative residual?
