a$)$ Develop a $5-$week moving average to forecast air travel passengers from week $6$ to week $19.(1$ pts$)$

b$)$ Estimate demand again for week $6$ to week $19$ within a $5-$week weighted moving average in which passengers for air travel in the most recent week are given a weight of $5,3,2$ and passengers in the other $2$ weeks are each given a weight of $1.(2$ pts$)$

c$)$ Compute the forecasts for each week using exponential smoothing, with an initial forecast for week $6$ of $425$ passengers. Use $=0\mathrm{.}25.(2$ pts$)$

d$)$ Using MAD, which of the three forecasting methods is best? $(1$ pts$)$

e$)$ Using MSE, which of the three forecasting methods is best? $(1$ pts$)$ f$)$ Using MAPE, which of the three forecasting methods is best? $(1$ pts$)$
