1. Forecast the demand for week 7 using a five-period moving average? (Marks 0.5) (word count maximum:100)
2. Forecast the demand for week 7 using a three-period weighted moving average. Use the following weights: W1 = .5, W2 = .3, W3 = .2.? (Marks 0.5) (word count maximum:100)
3. Forecast the demand for week 7 using exponential smoothing. Use an value of .1 and assume the forecast for week 6 was 602 units? (Marks 1) (word count maximum:100)
4. What assumptions are made in each of the above forecasts? (Marks 0.5) (word count maximum:150)
