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), and then divide that difference by the predicted number of attendees:
Difference = Predicted number of attendees - Actual number of attendees = 275 - 265 = 10
Percent Error = (Difference / Predicted number of attendees) * 100
Percent Error = (10 / 275) * 100 = 0.03818...
Rounding to the nearest hundredth percent, the percent error is 0.04%.
Therefore, the correct answer is:
0.04%
