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?

[tex]\text{Percent error}=\dfrac{|\text{Expected value-Actual value}|}{\text{Actual value}}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{|2.8-3.5|}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{0.7}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=20\%[/tex]

Therefore, the zookeeper’s percent error = 20 %

The percentage of any value can be predicted for denoted every value compared with 100. Thus, the zookeeper’s percent error is 20 %.

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.

Therefore,

The expected weight is 2.8 pounds.

The actual weight is 3.5 pounds.

So, the formulated way to represent the error percentage is given below:

[tex]\begin{aligned}\rm{Percentage \;Error}&=\dfrac{\rm{Expected\;Weight-Actual \;Weight}}{\rm{Actual\; Weight}} \times 100\\&=\dfrac{3.5-2.8}{3.5} \times 100\\&=\dfrac{0.7}{3.5} \times 100\\&=20 \; \% \end{aligned}[/tex]

Thus, the zookeeper’s percent error is 20 %.
