Answer: Sample 4
Step-by-step explanation:
We know that the percent error =\(\frac{|\text{actual amount- stated amount}|}{\text{actual amount}}\times100\)
Sample 1
Percent error\(=\frac{|20.1-20|}{20.1}\times100=\frac{0.1}{20.1}\times100=0.497512437811\%\approx0.50\%\)
Sample 2
Percent error\(=\frac{|31.9-32|}{31.9}\times100=\frac{0.1}{31.9}\times100=0.313479623824\%\approx0.31\%\)
Sample 3
Percent error\(=\frac{|35.9-36|}{35.9}\times100=\frac{0.1}{35.9}\times100=0.27.85\%\approx0.28\%\)
Sample 4
Percent error\(=\frac{|64.1-64|}{64.1}\times100=\frac{0.1}{64.1}\times100=0.1560062\%\approx0.16\%\)
We can see Sample 4 had the least percent error .
