The file [[http://dananne.org/fu/courses/math-241/R/pearson.txt|http://dananne.org/fu/courses/math-241/R/pearson.txt]] contains the data from Karl Pearson's study of the heights of 1078 fathers and sons discussed in Section 8.1. The data is in a table, with the first column labeled "Father" and the second column labeled "Son". 

  - Use this data to create a scatter diagram with regression line.
  - 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?
