Quizplus · Accepted Answer

To find the four-period moving average forecast for period 5, we need to add up the first four values and divide by 4.

(11 + eb + 12 + c9) / 4 = 97 / 4 = 24.25

Therefore, the forecasted value for period 5 is 24.25. However, since this time series appears to be composed of hexadecimal numbers, we need to convert this result to hexadecimal.

24.25 ≈ 18 in hexadecimal

Therefore, the best choice is C: 20.
