The dependent variable is absenteeism (ABSENT). The explanatory variable is seniority (SENIOR). The goal is to express the relationship between absenteeism and seniority in the form of an equation. Based on an examination of scatterplots and residual plots, do any assumptions of the linear regression model appear to be violated? If so, which one (or ones)? If any violations are detected, suggest possible corrections. Rerun the regression with the suggested corrections and compare your results to the original results. Be sure to do residual pots for the model using the suggested correction. Which model do you prefer and why?
