Twenty illicitly made tablets containing paracetamol and caffeine were submitted to the forensic laboratory by narcotic officers, Singapore

Question 1.3

Twenty illicitly made tablets containing paracetamol and caffeine were submitted to the forensic laboratory by narcotic officers. What would be the most suitable sampling plan for this analysis?

1. To sample one tablet for testing since both paracetamol and caffeine are not controlled.
2. Since the tablets were illicitly made, all twenty tablets should be sampled.
3. A hypergeometric sampling plan is good so that the result can be inferred to the entire twenty tablets,
4. Sampling of five tablets is a good compromise since paracetamol and caffeine are not controlled and the tablets are illicitly made.
5. Since there are two non-controlled drugs in the tablets, a sampling of at least ten tablets is needed.
