Bud N. Chemist must determine the density of a mineral sample. His five trials yield densities of 5.15 g/cm3, 4.83 g/cm3, 5.08 g/cm3, 4.97 g/cm3, 5.12 g/cm3. Independent studies found the correct density to be 5.06 g/cm3. Which of the following is incorrect? a. The mean of his analysis is 5.03 g/cm3 indicating an error of 0.03 g/cm3 from the correct density B.His data has a standard deviation of 0.017 g/cm3 C.His data has a relative standard deviation of 2.60% D. He can report his analyzed density as 5.0±0.2 g/cm3 at a 95% confidence level E. The true value (population mean) is found within the confidence interval of Bud’s work
