1. What is the forecast for May based on a weighted moving average applied to the following past demand data and using the weights: .40 and .60 (largest weight is for most recent data & round to one decimal place)?

Nov.	Dec.	Jan.	Feb.	Mar.	April
3	6	9	2	8	6

		4.8
		6.8
		7.2

2. Given an actual demand this period of 103, a forecast value for this period of 105, and an alpha of .4, what is the exponential smoothing forecast for next period?

		105.8
		104.2
		102.2
		103.8

3. Suppose that the actual demand in January and February was 7 units and 9 units respectively. Assume that the forecast for January was 5 units. If the firm uses exponential smoothing with an alpha value of .20 - Determine the forecast for March? (Round answers to two decimal places.)
