PLEASE ANSWER ALL PARTS!!

(b) Compute MSE using the average of all the data available as the forecast for the next period. (Round your answer to two decimal places.) MSE = What is the forecast for month 8 ? (c) Which method appears to provide the better forecast? The average of all the previous values provides a better forecast, because its MSE is smaller than the MSE using the most recent value. The most recent value provides a better forecast, because its MSE is smaller than the MSE using the average of all the previous values. The average of all the previous values provides a better forecast, because its forecast for month 8 is larger than the month 8 forecast using the most recent value. The most recent value provides a better forecast, because its forecast for month 8 is smaller than the month 8 forecast using the average of all the previous values
