Develop forecasts for periods 7 through 10 for the demand data in the table below, using

a) a three period weighted moving average using 0.6 (for oldest data), 0.3, and 0.1 (for most recent data).

b) exponential smoothing with alpha = 0.7. Use a 6th period forecast of 135 as the starting point for the

exponential smoothing technique.

c) Calculate MAD and indicate which one of these two forecasting approaches is better for this data. Provide comments regarding results.

Period	Actual	WMA	Exp. Smoothing
1	64
2	84
3	91
4	97
5	115
6	135
7	137
8	144
9	153
10	171
