Like father, like son: In 1906, the statistician Karl Pearson measured the heights of 1078 pairs of fathers and sons. The following table presents a sample of 7 pairs, with height measured in inches, simulated from the distribution specified by Pearson. The least-squares regression line y = b + bx = 42.7601 +0.4033x, s = 2.378781, (x-x) = 46.12, and x = 70.20 are known for this data.
