Product description
6. For the purpose of quality control, we determined the density d of the liquid medicinal product - otinum (ear drops in vials of 2 g / 10 ml) by the pycnometric method and found its density in five parallel determinations to be, g / ml: 1.058; 1.059; 1.060; 1.060; 1.061. Calculate the confidence interval d±Δd and the relative error e of the average density determination at a confidence level P=0.95. Answer:
The method for detecting gross misses is to calculate the value of the Q-criterion: d±Δd=1.060±0.001 g/ml e=0.09%.
