Julian and Brittany mailed 275 wedding invitations to family and friends and predicted that they would all attend. Only 265 out of 275 people committed to attending the wedding. Calculate the percent error in their prediction. Round your answer to the nearest hundredth percent.(1 point)
The absolute difference between the predicted number of attendees and the actual number of attendees is 275 - 265 = <<275-265=10>>10.
The percent error is (10 / 275) * 100 = 3.64%.
Rounding to the nearest hundredth percent, the percent error is 3.64%. Answer: \boxed{3.64}.
