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 20 3x weight If you had measured the tail length in centimeters instead of millimeters 1 centimeter 10 millimeters what w slope of the regression line be O 3 3 10 30 O 0 3
