Compute the one$-$step$-$ahead three$-$month and six$-$month moving$-$average forecasts for July through December. What effect does increasing N from $3$ to $6$ have on the forecasts? f$)$ Use the arithmetic average of the first six months of data as a baseline to initialize the exponential smoothing. $$ Determine the one$-$step$-$ahead exponential smoothing forecasts for August through December, assuming $=0\mathrm{.}2.$ Compare the accuracy of the forecasts obtained in part $($a$)$ with the one$-$stepahead six$-$month moving$-$average forecasts determined in Problem $5.$ Comment on the reasons for the result you obtained in part $($b$)$
