Given the following demand data, compute a simple exponential smoothing forecast for alpha values of $0\mathrm{.}2$ and $0\mathrm{.}4.$ 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.
