Need help on D and E.

(a) Given the following monthly labor figures, make a forecast for June using a three-period moving average and a five-period moving average. (Round answers to 2 decimal places, eg. 15.25.) Month Actual Values January 33 February 43 March 43 April 42 May 44 3-Period Moving Average 43 S-Period Moving Average 41 (b) What would be the forecast for June using the nave method? (Round answers to 2 decimal places, eg. 15.25.) Forecast for June (c) If the actual labor figure for June turns out to be 43, what would be the forecast for July using each of these models? (Round answers to 2 decimal places, eg. 15.25.) 3-Period Moving Average 43 5-Period Moving Average 43 Nave method 43 (d) Compare the accuracy of these models using the mean absolute deviation (MAD). (Round answers to 2 decimal places, eg. 15.25.) MAD (3-period) MAD (5-period) MAD (naive) (e) Compare the accuracy of these models using the mean squared error (MSF). (Round answers to 2 decimal places, eg. 15.25.) MSE (3-period) MSE (5-period) MSE (naive)
