a) The forecasted demand for the week of October 12 using a 3-week moving average = pints (round your response to two decimal places).
b) Using a 3-week weighted moving average, with weights of 0.15, 0.25, and 0.60, using 0.60 for the most recent week, the forecasted demand for
the week of October 12 = pints (round your response to two decimal places and remember to use the weights in appropriate order the largest
weight applies to most recent period and smallest weight applies to oldest period.)
c) If the forecasted demand for the week of August 31 is 350 and α = 0.30, using exponential smoothing, develop the forecast for each of the weeks
with the known demand and the forecast for the week of October 12 (round your responses to two decimal places).
