As part of the continuing strategic initiative to increase subscribers to the 3-For-All cable/phone/Internet services, the marketing department is closely monitoring the number of subscribers.

To help do so, forecasts are to be developed for the number of subscribers in the future. To accomplish this task, the number of subscribers for the most recent 24-month period has been determined and is stored in AMS16.

1. Analyze these data and develop a model to forecast the number of subscribers. Present your findings in a report that includes the assumptions of the model and its limitations.

Forecast the number of subscribers for the next four months.

2. Would you be willing to use the model developed to forecast the number of subscribers one year into the future? Explain.

3. Compare the trend in the number of subscribers to the number of new subscribers per month stored in AMS13. What explanation can you provide for any differences?
