I got sample two......I hope this helps but im 50% sure I might be wrong sorry, please don't hate me if I get it wrong

Answer:

Sample 2 has least percent error.

Step-by-step explanation:

The formula for percent error is

\(E=\frac{\text{Stated amount-Actual amount}}{\text{Actual amount}}\times 100\)

Percent error in sample 1:

\(E_1=\frac{14-13.7}{13.7}\times 100\approx 2.19\)

The percent error in sample 1 is 2.19.

Percent error in sample 2:

\(E_2=\frac{24-24.4}{24.4}\times 100\approx -1.64\)

The percent error in sample 2 is 1.64.

Percent error in sample 3:

\(E_3=\frac{25-25.8}{25.8}\times 100\approx -3.1\)

The percent error in sample 3 is 3.1.

Percent error in sample 4:

\(E_4=\frac{39-40.2}{40.2}\times 100\approx -2.99\)

The percent error in sample 4 is 2.99.

Therefore sample 2 has least percent error.
