7. Both simple exponential smoothing method and Holt's method (exponential smoothing with trend and without seasonality) are being used to forecast weekly car sales at Fairfax Toyota. Suppose the base is initially estimated to be 25 cars per week, and the trend is estimated to be 1 cars per week. Assume a =B=0.2. Suppose the actual demand during week 1 was 22. (a) (4) What are the two implications of simple exponential smoothing method? (b) (3) Forecast the number of cars to be sold during week 3 (i.e., 2 weeks later) using simple exponential smoothing method (c) (4) Continue part (b) using Holt's method (d) (3) During week 2, we observed that the actual demand is 28. Forecast the number of cars to be sold during week 3 (i.e., 1 week later than the second week) using simple exponential smoothing method (e) (4) Continue part (d) using Holt's method
