Results

The percent error between 75 and 80 is 6.667%

Solution:

Given: Accepted Value = 75 , Observed Value = 80

Percent Error Formula

Percent Error = | (Observed Value − Accepted Value) / Accepted Value | × 100  

Substitute values into the formula and solve:

Percent Error = | (80 − 75) / 75 | × 100  

= | (5) / 75 | × 100  

= | 0.067 | × 100  

= 6.667% (three decimal places)

Percent Error = 6.667%
