To begin trying to instill an ordering process, Blake needs to first establish demand forecasts.

Blake will begin looking at demand for lettuce at the Audubon farmers market. Use the

historical demand of lettuce provided in your case data to forecast demand at the Audubon

location for the next four weeks $($Week $8-11),$ using the following methods:

a$.4-$period moving average

b$.$ Exponential$-$smoothing with $=0\mathrm{.}1$

c$.$ Exponential$-$smoothing with $=0\mathrm{.}6$

d$.($Optional: a time series regression model$)$

Note $1$: You can assume Blake estimated there would be a demand of $1800$ pounds of lettuce in

Week $7.$

Note $2$: Assume the following actual demand occurs. Blake will not know this demand until after

it has occurred but can use it in forecasting demand in future weeks $($i$.$e$.,$ actual demand in Week

$8$ can be used to forecast demand for Week $9)$ and for error calculations in the following question.

This actual demand data should not be included as input data for your time series regression

model if you are creating one.

$$ Week $8$: $1,900$ pounds

$$ Week $9$: $2,000$ pounds

$$ Week $10$: $1,750$ pounds

$$ Week $11$: $1,975$ pounds
