(Round your answer to two decimal places.) Compute the MSE for the five-week moving average forecasts. (Round your answer to two decimal places.) (c) What appears to be the best number of weeks of past data (three, four, or five) to use in the moving average computation? MSE for the three-week moving average is 12.58. O Three weeks appears to be best, because the three-week moving average provides the smallest MSE. O Three weeks appears to be best, because the three-week moving average provides the largest MSE. O Four weeks appears to be best, because the four-week moving average provides the smallest MSE. O Five weeks appears to be best, because the five-week moving average provides the smallest MSE.
