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:

Week Forecast Method 1 Actual Demand 1 0.95 0.72 2 1.08 1.05 3 0.97 0.96 4 1.20 1.00

Week Forecast Method 2 Actual Demand 1 0.77 0.72 2 1.21 1.05 3 0.88 0.96 4 1.15 1.00

he MAD for Method 1 =

0.1180.118

thousand gallons (round your response to three decimal places).

Part 3

The mean squared error (MSE) for Method 1 =

thousand gallons2

(round your response to three decimal places).

Part 4

The MAD for Method 2 =

thousand gallons (round your response to three decimal places).

Part 5

The mean squared error (MSE) for Method 2 =

thousand gallons2

(round your response to three decimal places).
