Question

A zookeeper predicted the weight of a new baby elephant to be 267 pounds when it was born.The elephant actually weighed 299 pounds at birth.What was the percent error of the zookeeper prediction.

Answer 1

Percentage error of zookeeper's prediction = 10.70%

Explanation:

Weight of baby elephant predicted by zookeeper = 267 pounds

Actual weight of the elephant = 299 pounds

Percent Error =
`\frac\left {Actual weight}* 100`
`=(\left |267-299\right |)/(299)* 100`

`=(\left |-32\right |)/(299)* 100`
`=(32)/(299)* 100`
`=10.70\%`
