a) Predict demand for June using Weighted Moving Average (n=3) with w 3=0.7 for May, w2 =0.2 for April, and w 1=0.1 for March. b) What is the forecast for March using exponential smoothing with alpha =0.4 ? Question 2 refers to the following : Demand for the last three months was: a) Predict demand for January using Holt's model under alpha =0.4 and beta =0.5. ( 3 points) b) What is a level of January (L1) using Holt's model under alpha =0.5 and beta =0.5 ? (3 points) c) Predict demand for February using Holt's model under alpha =0.4 and beta =0.5.
