The Sun Devils Corporation is deciding which of two forecasting models to use. The forecasts for the two models and actual demand are provided below:

		MODEL 1	MODEL 2
MONTH	SALES	FORECAST	FORECAST
1		175	150	180
2		200	220	220
3		185	185	180
4		170	190	195
5		155	130	135
6		170	155	165
7		150	140	160
8		165	175	170
9		175	195	160
10		165	140	165

Compute the MAD, MAPE, and RSFE for the two forecasting methods. Do not round intermediate calculations. Round your answers for the MAD and MAPE to two decimal places and for the RSFE to the nearest whole number. Use a minus sign to enter a negative value, if any.
