a) The forecasted demand for the week of October 12 using a 3-week moving average = _______ pints (round your response to two decimal places).
Answer:
From the given data we need to find the Moving average.
Moving average = Average demand in 3 week period.
Moving average upto Oct 12 =
[Average demand in (September 21) + (September 28) + (October 5)] / 3
= 378 + 366 + 378 / 3
= 1,122 / 3
= 374.
Forecast the demand for the week of October 12 using a 3-week moving average = 374 points.
