Exhibit 2. Exhibit 2. Consider the following historical demand data: (Double check: Total demand for 7 periods is 635) Period 1 2 3 4 5 6 7 Demand 85 83 89 99 84 96 99 Question 30 (1 point) Refer to Exhibit 2. Calculate the tracking signal for the 3-period moving average model including periods 4 to 7. Select the closest value. OTS=2.37 TS=1.54 TS=18.33 TS-93 TS-5.6 Question 31 (1 point) Refer to Exhibit 2. Calculate the exponential smoothed forecast for period 8. Use alpha 0.3 and use 85 as initial forecast for period 1. 87 96 99 Refer to Exhibit 2. Using weights of 0.5; 0.3; and 0.2; calculate the weighted moving average forecast for period 8. 99 98 95.1 92.99 85 Question 33 (1 point) Refer to Exhibit 2. Estimate a regression to calculate a trend (calculate the y- intercept; slope); and forecast the trend model. What is the slope? 4.68 -1.24 1.15 2.25 Question 34 (1 point) Refer to Exhibit 2. What is the trend forecast for t=8? 95.46 99.71 90.71 102.48 86.21 Question 35 (1 point) Refer to Exhibit 2. Calculate the MAD of the trend model for periods 4 to 7. MAD=-2.14 MAD=0 MAD= 1.12 MAD= 2.14
