The manager of a small health clinic would like to use exponential smoothing to forecast demand for laboratory services in the facility. However, she is not sure whether to use a high or low value of. To make her decision, she would like to compare the forecast accuracy of a high and low on historical data. She has decided to use an =0.7 for the high value and =0.1 for the low value.

(a)

Given the following historical data, which do you think would be better to use? (Round answers to 2 decimal place, e.g. 15.25)

Week		Demand (lab requirements)
1		330
2		343
3		315
4		387
5		380
6		359

Forecasts using = 0.1, MAD
Forecasts using = 0.7, MAD
