$($b$)$ Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of $=0$

Using $=0\mathrm{.}1$MSE is $,$ and using $=0\mathrm{.}2$ MSE is $,$ so we would $p$

$($c$)$ Are the results the same if you apply MAE as the measure of accuracy? $($Round your answers to Using $=0\mathrm{.}1$MAE is $,$ and using $=0\mathrm{.}2$MAE is $,$ so the results

$($d$)$ What are the results if MAPE is used? $($Round your answers to two decimal places.$)$

Using $=0\mathrm{.}1$MAPE is $\%,$ and using $=0\mathrm{.}2$MAPE is $\%,$ so
