Use the following information to compute a single exponential smoothing model forecast with a smoothing constant ( =0.30 ) to produce a forecast for period 10 . (Note: at is the actual demand for the period.) Use 115 as the initial forecast. Click the icon to view the demand for the previous 9 periods. Fill-in the table below for a single exponential smoothing forecast (enter your responses rounded to one decimal place). The forecast for period 10 is (Enter your response rounded to one decimal place.) \begin{tabular}{cc} & \\ \hline Period & at \\ \hline 1 & 115 \\ 2 & 117 \\ 3 & 182 \\ 4 & 133 \\ 5 & 107 \\ 6 & 96 \\ 7 & 177 \\ 8 & 176 \\ 9 & 144 \\ \hline \end{tabular}
