Given the following demand data, compute a simple exponential smoothing forecast for alpha values of $0\mathrm{.}2$ and $0\mathrm{.}5.$ Use the actual value in Period $1$ as your starting forecast in Period $2.$

Note: Round all answers to two decimal places. Use these rounded answers when computing subsequent answers.

$\backslash$table$[[$Period$,=0\mathrm{.}2,=0\mathrm{.}5$Monthly attendance at financial planning seminars for the past $24$ months, and forecasts and errors for those months, are shown in the following table. Determine if the forecast is working by computing a tracking signal, beginning with month $10,$ updating MAD with exponential smoothing. Use an alpha value of $0\mathrm{.}2.$

Note: Round all your calculations to three decimal points.
