Explanation / Answer

1) dependent variable

2) 3- period Moving average forecast for period 4 = (Demand for period 3 + Demand for period 2 + Demand for period 1)/3

= (13250 + 12400 + 10000)/3

= 11883.33 = 11883

3) 4- period moving average forecast for period 5 = .05*Period 1 + .15*Period 2 + .30*Period 3 + .50*Period 4

= .05*10000 + .15*12400 + .30*13250 + .50*14750

= 13710 Correct option
