Chapter 7, Problem AP2.14(choose chapter or problem)
Section I: Multiple Choice Choose the best answer for each question. 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 childs 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.
