For a class project, you measure the weight in grams (g) and the tail length in millimeters (mm) of a group of mice. The equation of the least-squares line for predicting tail length from weight is: predicted tail length = 19 + 5 (Weight) By looking at the equation for the regression line, what can you tell about the correlation between weight and tail length is?
