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		33
February		44
March		43
April		41
May		49

3-Period Moving Average		enter forecast for June using 3-Period Moving Average
5-Period Moving Average		enter forecast for June using 5-Period Moving Average

(b) What would be the forecast for June using the nave method? (Round answers to 2 decimal places, e.g. 15.25.)

(c) If the actual labor figure for June turns out to be 47, 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		enter forecast for July using 3-Period Moving Average
5-Period Moving Average		enter forecast for July using 5-Period Moving Average
Nave method		enter forecast for July using Nave 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)		enter the mean absolute deviation
MAD (5-period)		enter the mean absolute deviation
MAD (nave)		enter the mean absolute deviation

(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)		enter the mean squared error
MSE (5-period)		enter the mean squared error
MSE (nave)		enter the mean squared error
