The following table represents the annual production volume and the ending inventory to be hold as margin of safety in relation to the annual production volume over $5$ years.

Use the exponential smoothing method to forecast the production volume and total quantity of inventory for the fourth year, then explain the results by comparing them as a percentage for each year. $\{$You need to know that the forecasted value of production volume for the first year was $95,000$ units, and the forecasted quantity of inventory for the first year was $21,000$ units$\}.$ Given that $\backslash$alpha $=0\mathrm{.}9.$
