The sales data for this product in the past 12 months is shown below (Note that month 1 refers to sales made 12 months ago. Month 12 refers to sales made last month.): Month Sales (in millions of packs) 1 1335 2 1334 3 1340 4 1342 5 1353 6 1358 7 1375 8 1376 9 1407 10 1423 11 1470 12 1498 3. First, the manager wants to see how a moving average would perform (irrespective of whether or not this is a suitable method for this data). Compute 3-month moving average forecasts of sales for months 4 to 12. What is the forecast for the 10th month? If your answer is not an integer, provide at least three decimal places, e.g., 7.500.
