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