Does the three-month or four-month moving average provide more accurate forecasts based on MSE? Explain.The three-month moving average provides more accurate forecasts, because its MSE is smaller than that of the four-month movingaverage.The three-month moving average provides more accurate forecasts, because its MSE is larger than that of the four-month movingaverage.The four-month moving average provides more accurate forecasts, because its MSE is smaller than that of the three-month movingaverage.The four-month moving average provides more accurate forecasts, because its MSE is larger than that of the three-month movingaverage.(c) Using the more accurate approach, what is the moving average forecast for the next month?
