The following results were obtained for the determination of calcium in a NIST limestone sample: % = 50.31, 50.22, 50.38, 50.19, and 50.45. Five gross samples were then obtained for a carload of limestone. The average percent values for the gross samples were found to be 49.46, 50.11, 49.62, 49.76, and 50.30. Calculate the overall relative standard deviation, the relative standard deviation of the method, and the relative standard deviation of the sampling process.
