Given the following demand data, compute a simple exponential smoothing forecast for alpha values of 0.2 and 0.5. Use the actual value in Period 1 as your starting forecast in Period 2. (Round all your calculations to two decimal points.) \begin{tabular}{|c|c|c|} \hline & =0.2 & =0.5 \\ \hline Period & Forecast & Forecast \\ \hline 1 & & \\ \hline 2 & & \\ \hline 3 & & \\ \hline 4 & & \\ \hline 5 & & \\ \hline 6 & & \\ \hline 7 & & \\ \hline 8 & & \\ \hline 9 & & \\ \hline 10 & & \\ \hline 11 & & \\ \hline 12 & & \\ \hline \end{tabular}
