4. 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 Actual Week Forecast Method 1 Demand Week Forecast Method 2 Demand 1 0.85 0.72 1 0.80 0.72 2 1.05 0.98 2 1.21 0.98 3 0.95 1.00 3 0.90 1.00 4 1.20 1.00 4 1.15 1.00 a) [1 pt] The MAD for Method 1 = thousand gallons (round your response to three decimal places). b) [1 pt] The mean squared error (MSE) for Method 1 = thousand gallons (round your response to three decimal places). c) [1 pt] The MAPE for Method 1 = % (round your response to two decimal places). d) [1 pt] The MAD for Method 2 = thousand gallons (round your response to three decimal places). e) [1 pt] The mean squared error (MSE) for Method 2 = thousand gallons2 (round your response to three decimal places). f) [1 pt] The MAPE for Method 2 = % (round your response to two decimal places). cm
