Problem 12-2
| Given the series of demand data below |
| Period: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Demand: | 36 | 32 | 60 | 41 | 21 | 41 | 32 | 39 | 29 | 45 |
| a. | Calculate the forecasts for periods 7 through 11 using moving average models with n = 2, n = 4, and n = 6. (Round your intermediate calculations and final answers to 1 decimal place.) |
| Week | n = 2 |
n = 4 |
n = 6 |
| 7 | |||
| 8 | |||
| 9 | |||
| 10 | |||
| 11 | |||
| b-1. |
Calculate the bias and MAD for each set of forecasts. |
| Moving Average Forecast | |||
| n = 2 | n = 4 | n = 6 | |
| Bias | |||
| MAD | |||
| b-2. |
