MSE values based on the two$-$ and three$-$period moving average are $858\mathrm{.}00$ and $\backslash (1,176\mathrm{.}98\backslash ),$ respectively.

Find the best single exponential smoothing model by evaluating the MSE from $0\mathrm{.}1$ to $0\mathrm{.}9,$ in increments of $0\mathrm{.}1.$ Do not round intermediate calculations. Round your answers to two decimal places. The model based on a smoothing constant of is the best. How does this model compare with the moving average models?
