Answer:
The correct answer is - about 60%
Step-by-step explanation:
Given:
predicted value: 8 inches
measured value - 20 inches
formula:
Prediction percentage error is the error or differences between the prediction made and the observed or actual value. Calculation of the percentage error by the following equation.
prediction percentage error = (measured value - predicted value)*100/measured value
solution:
putting value in the formula
= (20-8)*100/20
= 12*5
= 60 %
