5-18, Sales of Cool-Man air conditioners have grown steadily during the past five years.
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.
5-19, Using smoothing constants of 0.6 and 0.9, develop forecasts for the sales of Cool-Man air conditioners (see Problem 5-18).
5-22, Using the trend projection method, develop a forecasting model for the sales of Cool-Man air conditioners (see Problem 5-18).
The solution provides quantitative analysis of sales.
