Problem 3 Hospitality Hotels forecasts monthly labor needs. (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, e.g. 15.25.) Month Actual Values January 35 February March 38 April 42 May 47 44 3-Period Moving Average 5-Period Moving Average (b) What would be the forecast for June using the naive method? (Round answers to 2 decimal places, e.g. 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, e.g. 15.25.) 3-Period Moving Average 5-Period Moving Average Nalve method (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, e.g. 15.25.) 3-Period Moving Average 5-Period Moving Average Naive method (d) Compare the accuracy of these models using the mean absolute deviation (MAD). (Round answers to 2 decimal places, e.g. 15.25.) MAD (3-period) MAD (5-period) MAD (naive) (e) Compare the accuracy of these models using the mean squared error (MSE). (Round answers to 2 decimal places, e.g. 15.25.) MSE (3-period) MSE (5-period) MSE (naive)
