Refer to the gasoline sales time series data in the given table. Week 1 2 3 4 5 6 7 8 9 10 a. Compute four-week and five-week moving averages for the time series. Round your answers to two decimal places. 11 Week 12 1 2 3 4 5 6 7 8 9 10 11 12 18 22 17 15 21 17 22 Sales Moving Average Moving Average 18 22 19 Sales (1000s of gallons) 14 23 18 22 18 22 17 15 21 17 22 4-Week 19 14 23 5-Week b. Compute the MSE for the four-week and five-week moving average forecasts. Round your intermediate calculations and final answers to two decimal places. MSE for four-week moving average = MSE for five-week moving average = c. What appears to be the best number of weeks of past data (three, four, or five) to use in the moving average computation? Recall that MSE for the three-week moving average is 12.89.
