A shoe manufacturer, using exponential smoothing with a= 0.1, has developed a January trend forecast of 400 units for women’s shoe. This brand has seasonal indexes of 0.80, 0.90, and 1.20, respectively, for the first 3 months of the year. Assuming that actual sales were 344 units in January and 414 units in February, what would be the seasonalized (adjusted) March forecast?
