30. Solving a chemistry problem

8. For the dosage form - tablets of amizole (amitriptyline hydrochloride) - during the quality control of the drug, the mass m of tablets was determined in five parallel analyzes and found, mg: 133; 133; 134;134; 135. Describe the reproducibility of the results of the analysis - calculate the confidence interval m ± Δm and the relative error e for determining the average weight of the amizole tablet at a confidence level P=0.95. Answer: m±Δm=(133.8±1.0 mg)%; e=0.7%
