In Exercise 3.14, two of the variables examined by the personnel director were age and number of absences during the past year. Using the data in file XR03014, generate a scatter diagram (with y = number of absences and x = age), fit a linear equation to the data, then determine and interpret the coefficients of correlation and determination.
In exercise
Compare the mean and median number of days absent for females (coded as g ender = 1) versus males (coded as gender = 2) within the company.
