Question

There are 311 students at Lincoln Heights Middle School. During a tour of the school, the principal tells a group of people that there are about 300 students at the school. What is the percent error in the principal's estimate? Round to the nearest tenth percent.

Answer 1

You will use Percent Error formula below;

Percent Error = ((Estimated value-Actual value)/Actual value) * 100%

Percent Error = ((300-311)/311) * 100%

Percent Error = (-11/311) * 100%

Answer is 3.54%

Round to the nearest tenth percent = 3.5%
