Question

Alicia estimated that the number of horses living in a stable was 26. The actual number of horses living in the stable was 30.

What is the percent error in Alicia’s estimate? If necessary, round to the nearest percent.

Answer 1

`\%\text{error}=\frac{|\text{estimated value}-\text{actual value}|}{\text{actual value }}\cdot100\%\\\\ \%\text{error}=(|26-30|)/(30)\cdot100\%\\ \%\text{error}=(|-4|)/(30)\cdot100\%\\ \%\text{error}=(4)/(30)\cdot100\%\\ \%\text{error}\approx13\%`
