Please show work on excel :D

An exponential smoothing model has been, along with the corresponding Mean Squared Error (MSE). Please use Solver to determine the best value for alpha, based on the MSE. Report the best value for alpha. \begin{tabular}{|c|r|r|r|} & & \multicolumn{1}{c|}{ alpha } & \multicolumn{1}{c|}{ MSE } \\ \cline { 3 - 4 } & & 0.4 & 1204.0 \\ \hline Week & Demand & F t & Et2 \\ \hline 1 & 1,000 & & \\ \hline 2 & 1,019 & 1,000.0 & \\ \hline 3 & 1,003 & 1,007.6 & \\ \hline 4 & 1,031 & 1,005.8 & \\ \hline 5 & 1,016 & 1,015.9 & 0.0 \\ 6 & 980 & 1,015.9 & 1289.8 \\ \hline 7 & 929 & 1,001.5 & 5263.2 \\ \hline 8 & 959 & 972.5 & 183.0 \\ \hline 9 & 932 & 967.1 & 1233.2 \\ 10 & 945 & 953.1 & 65.1 \\ \hline 11 & 981 & 949.8 & 970.8 \\ \hline 12 & 962 & 962.3 & 0.1 \\ \hline 13 & 1,028 & 962.2 & 4331.9 \\ 14 & 1,034 & 988.5 & 2069.3 \\ 15 & 999 & 1,006.7 & 59.4 \\ 16 & 961 & 1,003.6 & 1816.8 \\ \hline 17 & 1,004 & 986.6 & 303.7 \\ 18 & 965 & 993.5 & 814.8 \\ 19 & 955 & 982.1 & 735.9 \\ \hline 20 & 960 & 971.3 & 127.1 \\ \hline \end{tabular}
