LerIn 1906, the statistician Karl Pearson measured the heights of 1078 pairs of father and sons. The following table presents a sample of pairs, with height measured in inches, simulated from the distribution specified by Pearson. Father's Height Son's Height 73.6 74.9 66.7 68.9 70.1 73.3 68.3 68.3 72.3 71.9 73.6 76.5 69.3 71.4 Send data to Excel. Consider the least-squares regression line for predicting son's height from father's height. Test H0: β = 0 versus H1: β ≠ 0. Can you conclude that father's height is useful in predicting son's height? Use the α = 0.05 level of significance. [Choose one] There is enough evidence at the α = 0.05 level of significance to conclude that father's height is useful in predicting son's height.
