McCall$$s Garden Supply has seen the following annual demand for lime bags over the past $11$ years.

Forecast the next period's demand by using exponential smoothing with a smoothing constant of $0\mathrm{.}4.$

Assume that the initial forecasted value for Year$1$ is $6($thousand$)$ bags to begin the procedure.

Enter the value of MSE $($Mean Squared Error$)$ after using exponential smoothing with a smoothing constant of $0\mathrm{.}4.$

$*$Round your answer to two decimal places $($like $10\mathrm{.}52$; $11\mathrm{.}00$; $...).$

$*$Enter it as $6.$ Do not enter it as $6,000.$ The original data is already scaled to a thousand. Please check the data set$-$I.
