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	0.90	0.72
2	1.02	1.00
3	0.95	1.07
4	1.17	1.00

Week	Forecast Method 2	Actual Demand
1	0.80	0.72
2	1.21	1.00
3	0.92	1.07
4	1.11	1.00
