Herman Hahn is attempting to set an integrated forecasting and the inventory control system for his hardware store, Hahn’s Hardware. When Herman specifies that outdoor lights are the seasonal item on computer, he is prompted by program to input the seasonal factors by quarter. Unhappily, Herman hasn’t kept any historical data, but he estimates that first- quarter demand for lights is about 30 percent below average, the second quarter demand about 20 percent below average, third-quarter demand about average, and fourth- quarter demand about 50 percent above average. What must he input for seasonal factors?
