- Blank Filling Question. No work is required or graded. The amount of water used by the production facilities of a plant varies. Observations on water usage and other, possibly related, variables were collected for 17 months. The following model is fitted: USAGE = Bo + Bi TEMP + B2 PROD+ B3 DAYS+ B4 PAYR + Bs HOUR + E where the response variable is USAGE = monthly water usage (gallons/100) and the explanatory variables are TEMP average monthly temperature (°F) amount of production number of operating days in the month number of people on the monthly plant payroll PROD %3D DAYS = PAYR HOUR number of hours shut down for maintenance %3D Below is the selected SAS output with edit.
