1. Prepare a graph of the data. On this same graph plot a 12-month moving average forecast. Discuss any apparent trend and seasonal patterns.2. Use regression to develop a trend line that could be used to forecast monthly sales for the next year. Is the slope of this line consistent with what you observed in question 1? If not discuss a possible explanation.3. Use the multiplicative decomposition model on these data. Use this model to forecast sales for each month of the next year. Discuss why the slope of the trend equation with this model is so different from that of the trend equation in question 2.
