Herman Hahn is attempting to set up an integrated forecasting and inventory control system for his hardware store, Hahn$$s Hardware. When Herman indicates that outdoor lights are a seasonal item on the computer, he is prompted by the program to input the seasonal factors by quarter.

Unfortunately, Herman has not kept any historical data, but he estimates that first$-$ quarter demand for the 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 should he input for the seasonal factors?
