The correlation between the age and height of children under the age of 12 is found to be r = 0.60. Suppose we use the age x of a child to predict the height y of the child. What can we conclude?

(a) The height is generally 60% of a child’s weight.

(b) About 60% of the time, age will accurately predict height.

(c) Thirty-six percent of the variation in height is accounted for by the linear model relating height to age.

(d) For every 1 year older a child is, the regression line predicts an increase of 0.6 feet in height.

(e) Thirty-six percent of the time, the least-squares regression line accurately predicts height from age.
