Analyze the residual plot below and identify? which, if? any, of the conditions for an adequate linear model is not met. 5 15 25 2 -2 0 Explanatory Residuals A residual plot has a horizontal axis labeled Explanatory from less than 5 to 25 plus in increments of 10 and a vertical axis labeled residuals from less than negative 2 to 2 plus in increments of 1. A horizontal dashed line intersects the vertical axis at 0. A series of plotted points have no discernable pattern. Which of the conditions below might indicate that a linear model would not be? appropriate?
