And:

  1. The file 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”. Recall: If you use RStudio to directly import this file, change the “Separator” selection from “Tab” to “Whitespace”.
    1. Use this data to create a scatter diagram with regression line, treating the heights of the sons as the dependent variable.
    2. Plot the residuals.
  2. The file http://dananne.org/fu/courses/math-241/R/reading.txt contains data from a reading test administered to 40 elementary school students. The test was first given to the students in 1982 and then given a year later to the same students. The data is in a table, with the first column labeled “Y1982” and the second column labeled “Y1983”.
    1. Use this data to create a scatter diagram with regression line, treating the 1982 data as the x variable and the 1983 data as the y variable.
    2. Plot the residuals.
