Question

Transcribed Image Text: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 moving
average.
The three-month moving average provides more accurate forecasts, because its MSE is larger 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 four-month moving average provides more accurate forecasts, because its MSE is larger than that of the three-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.)
