Suppose that the growth rate of children looks like a straight line if the height of a child is observed at the ages of 24 months, 28 months, 32 months, and 36 months. if you use the regression obtained from these ages and predict the height of the child at 21 years, you might find that the predicted height is 20 feet. what is wrong with the prediction and the process used?
