Question
1. Develop a simple linear regression equation for starting salaries using an independent
variable that has the closest relationship with the salaries. Explain how you chose this
variable.
2. Present the simple lincar regression equation, identify and explain the cocfficient of
determination, intercept and regression coefficient, and significance of F-test. Based on this
analysis, is your regression equation "good for use"? Explain.
3. Provide a numeric example of how this regression equation may be used to predict students
starting salaries.
4. Develop a multiple regression equation for starting salaries using School Ranking, GPA, and
Experience as independent variables. Is this regression equation "good for use? Explain.
5. If the multiple regression equation in the previous question is not "good for use", how would
you suggest improving this multiple regression equation? Present the improved multiple
regression equation. Give a numeric example of how this improved multiple regression
equation may be used to predict students' starting salaries.
