My sales manager had predicted, before the business started, that year 1’s sales would be 410 computers.

What are required:

  1. Develop forecasts for years 2 through 6 by using exponential smoothing with a weight of alpha = 0.30
  2. Develop forecasts for the sales of Orange computers by using smoothing constants of 0.6 and 0.9
  3. Help me to propose the most accurate forecast in smoothing constant, based on forecast at no.2 above.
  4. Help me to critically evaluate the effect that the smoothing constant have on the forecast for Orange computers.
