If the error margin in an analytical study is 20 %. What is the region of accuracy?
10%
20%
80%
90%
80% to 90%
To determine the region of accuracy in an analytical study, you need to subtract the error margin from 100%.
In this case, the error margin is given as 20%. To find the region of accuracy, subtract 20% from 100%:
100% - 20% = 80%
Therefore, the correct answer is 80%. The region of accuracy in this analytical study is 80%.
