Answer:

Sample 2 has least percent error.

Explanation:

The formula for percent error is


E=\frac{\text{Stated amount-Actual amount}}{\text{Actual amount}}* 100

Percent error in sample 1:


E_1=(14-13.7)/(13.7)* 100\approx 2.19

The percent error in sample 1 is 2.19.

Percent error in sample 2:


E_2=(24-24.4)/(24.4)* 100\approx -1.64

The percent error in sample 2 is 1.64.

Percent error in sample 3:


E_3=(25-25.8)/(25.8)* 100\approx -3.1

The percent error in sample 3 is 3.1.

Percent error in sample 4:


E_4=(39-40.2)/(40.2)* 100\approx -2.99

The percent error in sample 4 is 2.99.

Therefore sample 2 has least percent error.
