Month Time Series
Value		 3-Month Moving
Average Forecast		 4-Month Moving
Average Forecast
1 9.5
2 9.3
3 9.4
4 9.6
5 9.9
6 9.8
7 9.8
8 10.5
9 9.9
10 9.7
11 9.6
12 9.6

Does the three-month or four-month moving average provide more accurate forecasts based on MSE? Explain.

The four-month moving average provides more accurate forecasts, because its MSE is larger than that of the three-month moving average.The three-month moving average provides more accurate forecasts, because its MSE is smaller than that of the four-month moving average.    The four-month moving average provides more accurate forecasts, because its MSE is smaller than that of the three-month moving average.The three-month moving average provides more accurate forecasts, because its MSE is larger than that of the four-month moving average.

(c)

Using the more accurate approach, what is the moving average forecast for the next month? (Round your answer to two decimal places.)
