The linear regression equation that models the relationship between the length of the hand and the length of the forearm (from wrist to elbow) is y = 1.618x. The correlation coefficient is 0.8. Which of the following is true? A. If the forearm length is 10 cm, then the hand length is 16.2 cm. B. If the hand length is 16 cm, then the forearm length is 25.9 cm. C. If the hand length is 12 cm, then the forearm length is 7.4 cm. D. The correlation between the variables is weak, so linear regression is not useful for predictions.
