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 6pairs, with height measured in inches, simulated from the distribution specified by Pearson.Father'sSon'sheightheight69.371.466.768.870.771.065.770.972.469.165.466.0Send data to Excel= 41.2733 are known for this data.
