To calculate the percent error, we first need to find the difference between the predicted number of attendees (275) and the actual number of attendees (265).
Difference = Predicted number - Actual number
= 275 - 265
= 10
Then, we can calculate the percent error using the formula:
Percent Error = (Difference / Predicted number) * 100
Percent Error = (10 / 275) * 100
= 3.6363636363636362...
Rounding to the nearest hundredth percent, the percent error is approximately 3.63%. Therefore, the correct answer is 3.63%.
