The sales manager had predicted, before the business started. That year 1's sales would be 410 air conditioners. Using exponential smoothing with a weight of a = 0.30, develop forecasts for years 2 through 6.
Problem 2: Using smoothing constants of 0.6 and 0.9, develop forecasts for the sales of Cool-Man air conditioners (see Problem above).
Problem 3: Using the trend projection method, develop a forecasting model for the sales of Cool-Man air conditioners (see Problem above).
