a) The forecasted demand for the week of October 12 using a 3-week moving average = 376.67 pints (round your
response to two decimal places).
b) Using a 3-week weighted moving average, with weights of 0.20, 0.35, and 0.45, using 0.45 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.)
