The accompanying data file contains 10 observations for $t$ and $y_t$. Bapicture Click here for the Excel Data File A 3-period moving average is plotted along with the actual series. 6. Comment on smoothing The jagged graph represents the original series and the smoother graph represents its 3-period moving average. The smoother graph represents the original series and the jogged graph represents its 3-period moving average. We cannot tell which graph represents the original series and which its 3-period moving average. b.1. Use the 3-period moving average to make in-sample forecasts. (Do not round intermediote calculations and round final answers to 2 decimol ploces.) b.2. Compute the resulting MSE and MAD. (Do not round intermediate calculations and round final answers to 2 decimal places.) c. Make a forecost for period 11. (Do not round intermediate calculations and round final answers to 2 decimol places.) Sheet1 Sheet2 Sheet3 A 3-period moving average is plotted along with the actual series. a.
