For the provided data, develop a regression model for overall satisfaction as a function of years of service and department that has the largest appropriate R2 value. Note that the categorical variable department has multiple levels and will require the use of multiple dummy variables. Which department, if any, has the highest impact on satisfaction? Click the icon to view the job satisfaction data. Determine the regression model for overall satisfaction as a function of years of service and department that has the largest R2. Let "Administrative" be the baseline department, let X1 represent Maintenance, let X2 represent Management, let X3 represent Production, let X4 represent Quality Control, and let X5 represent Shipping / Receiving, coding each department variable with a 1 if the person is in that department and 0 otherwise. In addition, let X6 represent Years. Enter the terms of the equation so that the Xk-values are in ascending numerical order by base. Select the correct choice below and fill in any answer boxes within your choice. (Type integers or decimals rounded to three decimal places as needed.)
