Answer 1

To calculate the percent error, we need to find the difference between the predicted number of attendees (275) and the actual number of attendees (265).

The difference is 275 - 265 = 10.

Then, we divide the difference by the predicted number of attendees and multiply by 100 to get the percent error.

Percent Error = (10/275) * 100 = 3.63%

So the correct answer is B. 3.63%.
