Also: For Karl Pearson's study of the heights of 1078 fathers and sons discussed in Section 8.1, we have $\bar{x} = 67.69$, $\bar{y} = 68.68$, $\mathrm{SD}_x = 2.74$, $\mathrm{SD}_y = 2.81$, and $r = 0.50$.
  - What is the equation of the regression line?
  - What does the regression line predict for the height of a son whose father is 65 inches tall?
  - What does the regression line predict for the height of a son whose father is 75 inches tall?


Answers:
  - $y = 0.51x + 34.16$
  - $67.31$
  - $72.41$
