Question $1$

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 simple moving average to project 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 $1.$

Develop, a trend line for the demand for fertilizer

Three different forecasts were developed for the demand for fertilizer. These three forecasts are a $3-$year moving average, a weighted moving average, and a trend line. Which one would you use? Explain your answer.
