Develop a three$-$period weighted moving average forecast for periods $4$ through $11.$ Use weights of $\backslash (0\mathrm{.}6,0\mathrm{.}3\backslash ),$ and $0\mathrm{.}1,$ with the most recent observation weighted the highest. Calculate the MFE, MAD, and MAPE values for periods $4$ through $10.$
