(b) Compare a three-month moving average forecast with the exponential smoothing forecast for a = 0.3. Compute the MSE for the three-month moving forecast. (Round your answer to two decimal places.) Compute the MSE for the exponential smoothing forecast for a = 0.3. (Round your answer to two decimal places.) Which provides more accurate forecasts using MSE as the measure of forecast accuracy? OA 3-month moving average provides the most accurate forecast using MSE. Both forecastes provide the same level of accuracy using MSE. An exponential smoothing forecast with a = 0.3 provides the most accurate forecast using MSE. (c) Using the more accurate forecast, what is the forecast for the next month? (Round your answer to two decimal places.)
