Only need help with part c. a. Calculate the MSE, MAD,

Only need help with part c.

a. Calculate the MSE, MAD, and MAPE for each forecast. (Round the MAPE answers to 2 decimal places and other answers to 1 decimal place.) b-1. Do all three measures of forecast errors provide the same conclusion (i.e., are they consistent) in this case? b-2. Do you expect consistent results in every case? will have a lower MAD and MAPE than c. Calculate 2S control limits for each forecast and determine if each forecasting process is in control. (Round the final answers to 2 decimal places.)
