Following are two weekly forecasts made by two different methods for the number of gallons of gasoline, in thousands, demanded at a local gasoline station. Also shown are actual demand levels, in thousands of gallons: Actual Demand Week Week 1 1 Forecast Method 1 0.85 1.08 0.92 1.17 Forecast Method 2 0.77 1.20 0.88 1.17 Actual Demand 0.72 0.98 0.96 1.00 0.72 0.98 0.96 1.00 2 2 3 3 4 4 The MAD for Method 1 = thousand gallons (round your response to three decimal places). The mean squared error (MSE) for Method 1 = thousand gallons? (round your response to three decimal places). The MAD for Method 2 = thousand gallons (round your response to three decimal places). The mean squared error (MSE) for Method 2 = thousand gallons? (round your response to three decimal places)
