Demand for the last four months was:Month ----Mar-Apr-May-JunDemand-----6---8-----10---8A) Predict the demand for July using each of these methods:1) A 3-period moving average2) Exponential smoothing with alpha equal to 0.20, April forecast is 6 (use naive to begin)3) Using the weights of .5, .3, and .2, what is the three-period weighted moving average forecast for JulyB) If the naive approach had been used to predict demand for April through June, what would the MAD have been for those months?
