solution

Would you use exponential smoothing with a smoothing constant of 0.3, a 3-year moving average, or a trend to predict the sales of Cool-Man air conditioners? Refer to Problems 5-21, 5-24, and 5-25.

Problems 5-21

Sales of Cool-Man air conditioners have grown steadily during the past 5 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 develop forecasts for years 2 through 6.

Problems 5-24

Use a three-year moving average forecasting model to forecast the sales of Cool-Man air conditioners (see Problem 5-21).

Problems 5-21

Sales of Cool-Man air conditioners have grown steadily during the past 5 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 develop forecasts for years 2 through 6.

Problems 5-25

Using the trend projection method, develop a forecasting model for the sales of Cool-Man air conditioners (see Problem 5-21).

Problems 5-21

Sales of Cool-Man air conditioners have grown steadily during the past 5 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 develop forecasts for years 2 through 6.
