Question

A convenience store recently started to carry a new brand of soft drink. Management is interested in estimating future sales volume to determine whether it should continue to carry the new brand or replace it with another brand. The following table provides the number of cans sold per week. Use the exponential smoothing (let

α=0.4

with an initial forecast for week 1 of

617)

methods to forecast demand for week

13.

Period	1	2	3	4	5	6	7	8	9	10	11	12
Sales	617	617	648	739	659	623	742	704	724	715	668	740

Obtain the exponential smoothing forecast.

The forecast for week 13 is =? nothing.
