Determine the regression model for overall satisfaction as a function of years of service and department that has the largest Upper R squared. Let$$ "Administrative" be the baseline$$ department, let Upper X $1$ represent$$ Maintenance, let Upper X $2$ represent$$ Management, let Upper X $3$ represent$$ Production, let Upper X $4$ represent Quality$$ Control, and let Upper X $5$ represent Shipping$/$ Receiving, coding each department variable with a $1$ if the person is in that department and $0$ otherwise. In$$ addition, let Upper X $6$ represent Years. Enter the terms of the equation so that the Upper X Subscript k$-$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.$)$
