To calculate the percent error, we need to find the difference between the predicted number of attendees and the actual number of attendees, and then divide that difference by the predicted number.
The predicted number of attendees was 275 and the actual number of attendees was 265.
The difference is 275 - 265 = 10.
To find the percent error, we divide the difference by the predicted number and multiply by 100.
Percent error = (10/275) × 100 = 3.64%
Rounded to the nearest hundredth percent, the percent error is 3.63%. Therefore, the correct answer is:
3.63%
