The predicted number of attendees was 275, but the actual number of attendees was 265.
To find the percent error, we use the formula:
Percent error = (|predictive value - actual value| / actual value) * 100
Percent error = (|275 - 265| / 265) * 100
= (10 / 265) * 100
= 0.038%
Therefore, the percent error in their prediction is 0.038%.
