John's parents recorded his height at various ages between 36 and 66 months. Below is the equation of the least-squares regression line of John's height (inches) on age (months) based on John's records. John's parents decide to use the least-squares regression line of John's height on age to predict his height at age 16 years (192 months). What conclusion can we draw? John's height, in inches, should be about half his age, in months. Such a prediction could be misleading, because it involves extrapolation. The parents will get a fairly accurate estimate of his height at age 16 years, because the data are clearly correlated.
