Question: In problem, the father-daughter height data, you found r .513.
a. Compute the regression coefficients a and b.
b. Use your scatterplot from problem and draw the regression line.
Problem: This problem is based on data published in 1903 by Karl Pearson and Alice Lee. In the original article, 1376 pairs of father-daughter heights were analyzed. The scores here produce the same means and the same correlation coefficient that Pearson and Lee obtained. For these data, draw a scatterplot and calculate r by both the raw-score formula and the blanched formula.
Father's height, X (in.) 69 68 67 65 63 73
Daughter's height, Y (in.) 62 65 64 63 58 63
