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	1.02	0.98
3	0.95	1.07
4	1.17	1.04

Week	Forecast Method 2	Actual Demand
1	0.77	0.72
2	1.19	0.98
3	0.90	1.07
4	1.11	1.04

Part 2

a. The MAD for Method 1 = enter your response here thousand gallons (round your response to three decimal places).

b. The mean squared error (MSE) for Method 1=______thousands gallons^2(round your response to three decimal places)

c. The MAD for method 2=____thousands gallons (round your response to three decimal places)

d. The mean squared error (MSE) for Method 2=____thousands gallons^2 (round your response to three decimal places)
