Read the case Tires for You, Inc. and answer the following questions:$1.$ Calculate a forecast using a simple three$-$month moving average$\mathrm{.}2.$ Calculate a forecast using a three$-$period weighted moving average. Use weights of $0\mathrm{.}60,0\mathrm{.}30,$ and $0\mathrm{.}10$ for the most recent period, the second most recent period, and the third most recent period, respectively$\mathrm{.}3.$ Calculate a forecast using the exponential smoothing method. Assume the forecast for period $1$ is $9,500.$ Use alpha $=0\mathrm{.}40\mathrm{.}4.$ Based on the three methods used to calculate a forecast for TFY$,$ which method produced the best forecast? Why? What measures of forecast error did you use? How could you improve upon this forecast?
