Which one would you use? Explain your answer. In Problems 5-17, Data collected on the yearly demand for 50- pound bags of fertilizer at Wallace Garden Supply are shown in the following table. Develop a 3-year moving average to forecast sales. Then estimate demand again with a weighted moving average in which sales in the most recent year are given a weight of 2 and sales in the other 2 years are each given a weight of Demand for Fertilizer Year (1,000s of Ba gs) 1 ........... 4 2 ........... 6 3 ........... 4 4 ........... 5 5 ........... 10 6 ........... 8 7 ........... 7 8 ........... 9 9 ........... 12 10 .......... 14 11 .......... 15
