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". - Use this data to create a scatter diagram with regression line, treating the heights of the sons as the dependent variable. - Plot the residuals. - The file [[http://dananne.org/fu/courses/math-241/R/reading.txt|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". - 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. - Plot the residuals.
