Question

If a method produces a random error for each measurement of 4%, but a percent error of equal to or less than 1% is required for this value for later analysis, what is the minimum number of measurements that must be collected and averaged

Answer 1

7.05

Step-by-step explanation:

Random error is = 0.282

Remember ( random error / total sum of errors ) x 100 = 4%

Which is 0.282/ total sum of errors = 428.2

Total sum of errors = 7.05
