i would like some help on this question about measuring forecast accuracy. Thank you!

Measuring Forecast Accuracy You are hired as a consultant to assess a firm's ability to forecast. The firm has developed a point forecast for two different currencies presented in the following table. The firm asks you to determine which currency was forecasted with greater accuracy. Show your calculation. (1 point) (hint: For each currency, compute the absolute forecast error as a percentage of realized (actual) value for each period, then calculate its average over the four periods. Compare the average forecast errors of the two currencies)
