Provide your forecast for Month $17$ using the moving average, weighted moving average, and exponential smoothing methods as follows:

a$)$ For the moving average, use a $3-$period moving average.

b$)$ Use a three$-$period weighted moving average. Unfortunately, you spilled water on the sheet with the weights to be used for the weighted moving average and this blurred the weight for the third most recent period. However, you can tell that the weights for the first and second most recent months are $0\mathrm{.}6$ and $0\mathrm{.}3$ respectively.

c$)$ For exponential smoothing, use an $\backslash$alpha $=0\mathrm{.}35,$ and the forecast for Month $6$ is $$0\mathrm{.}40.$
