12) This is a written question, worth 10 points. DO NOT place the problem code on the answer sheet. A proctor will fill this out after exam submission. Show all steps (work) on your answer sheet for full credit. The accompanying scatter plot (to the right) illustrated 40 the relationship between the time (in years) an employee works at a certain company compared the employee's job satisfaction, measured on a 50-point scale. 20- Part a: Identify the explanatory and response variables for this situation. Part b: Give the LSRL equation for this data. Part c: Find the correlation coefficient and the coefficient of determination for this data. What do each of these tell you about the relationship between the variables? Based on this information, do you think your answer in part c is a good model? Part d: Give the residual plot of this data (based on your linear model). What is the residual for an employee that has been with the company for 8 years? Part e: Propose an alternate model (non-linear) to represent this situation. Why did you choose this model
