Question

A zookeeper predicted that the weight of a newborn lion would be 2.8 pounds.

When the zoo’s lion gave birth, the newborn weighed 3.5 pounds.
What is the zookeeper’s percent error? Enter your answer in the box.

Answer 1

Zookeepers percent error was 20%.

Explanation:

Given:

Zookeepers Prediction of weight = 2.8 pounds

Actual weight = 3.5 pounds

Zookeepers error = Actual weight - Zookeepers Prediction of weight = 3.5 - 2.8 = 0.7 pounds

Now to find the percent error we divide the error by actual weight and then multiply by 100

Zookeepers percent error =
`\frac{\textrm{Zookeepers error}}{\textrm{actual Weight}}*100 =(0.7)/(3.5)*100 = 20\%`

Hence Zookeepers percent error is 20%.
