Question 3:

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: Forecast Actual Forecast Actual Week Method 1 Demand Week Method 2 Demand - 0.90 0.68 0.77 0.68 1.05 1.05 1.19 1.05 A W N . AWN - 0.97 1.07 0.90 1.07 1.22 0.97 1.11 0.97 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)
