A retail store wants to forecast its weekly units for toilet paper. Historical data $($in units$)$ for $10$ weeks are shown in the next slide. Using this chart, answer the following questions.

Develop a three period and four period moving average forecasts.

Which provides a better forecast $(3-$period or $4-$period moving average$)?$

Use a smoothing constant of $0\mathrm{.}2$ and $0\mathrm{.}5$ and calculate the exponential smoothing forecasts

Calculate MAPE, MAD & MSE for each smoothing constant. Which smoothing constant is preferred?

Would you choose MA or SES as the forecasting methodology for future periods?
