Problem $4($exponential smoothing$)$

Use the data to complete the following:

a$.$ Construct the worksheet for single$-$factor exponential smoothing with $=\mathrm{.}23$ to obtain the forecasts

for the months of February through December of Year $1$ and all of Year $2.$ Assume that the forecast

for January of Year $1$ is the same as the actual for January of Year $1.$

b$.$ Graph the actual values and the forecasted values for Years $1$ and $2.$ Does the forecasted value

provide "good fit" relative to the actual values? Justify your response.
