120. Solving a chemistry problem

2. When using a method in which the relative standard deviation of individual results must be ≤ 0.5%, the following data are obtained: 30.15; 30.55; 30.12. a) Calculate the absolute values of the standard deviations using the value of the range of values. b) Evaluate the reproducibility of these results by comparing it with a known relative standard deviation.
