Eighteen pairs of measurements were taken at random to estimate the relationship between variables X and Y. A least-squares line was fitted to the collected data. The resulting residual plot is shown. A residual plot is shown with 18 points scattered above and below the x-axis in such a way that the distance from the x-axis increases as you move from left to right. Which of the following conclusions is appropriate?
