2. Forecast demands for using weighted moving average. Please apply weights of 0.3 for most recent period, then 0.4 , then 0.3 3. Given the following data: Prepare a forecast using smoothing constant =0.40. a) Subjective estimate (for this example, use 60). b) First actual value (nave approach). 4. Given the following data: c) What are the exponential smoothing forecasts for periods 25 using =0.7 ? d) Use nave approach for 1st week
