Challenge Problems

Push your limits with challenges.

Question 1

A laboratory is consistently receiving a measurement of a pollutant as 20 ppm when using their current calibration. However, a re-evaluation shows inaccurately calibrated instruments were used, leading to a double-check against verified standards. How should the lab proceed?

💡 Hint: Think about the steps involved in ensuring reliability once error is discovered.

Question 2
