.Shaun estimated that the attendance at a college

Serggg [28]

Answer:

38.72%

Step-by-step explanation:

Estimated attendance = 1,000

The actual value of attendance = 1,632

We need to find the percent error of Shaun's estimate. Using the formula as follows :

$\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100$

Put all the values,

$\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%$

So, the percent error of Shaun's estimate is 38.72%.
