A researcher investigates the factors that are associated with the salaries of professors who teach courses at a major university. The researcher gathers data about the subject area and the salary per course for a random sample of professors.
- Run the appropriate test in Minitab and show output. What conclusions can you make?
- Obtain boxplots and residual plots for these data.
- Are the assumptions of an ANOVA reasonably satisfied? Explain in reference to the plots.
- If there is a difference in salaries run a Tukey’s test to show how the salaries for the different subject areas compare to each other. Describe what the results of the Tukey’s test tell you.
