Question

You estimate that a baby guinea pig weighs 3.5 ounces. The actual weight of the baby guinea pig is 3 ounces. Find the percent error. Round your answer to the nearest hundredth of a percent.

Answer 1

Percent Error = ((measured value)/(actual value) -1)*100%
  = (3.5/3 -1)*100%
  ≈ (1.16666667 - 1)*100%
  ≈ 0.1667*100%
  ≈ 16.67%
