Five gross samples were determined for a carload of limestone. The average percent MgO values for the gross samples were found to be 49.53, 50.12, 49.60, 49.87, and 50.49. Meanwhile, the following results were obtained for the determination of magnesium in a NIST magnesia sample: %MgO = 50.33, 50.22, 50.36, 50.21, and 50.44. Calculate the relative standard deviation associated with the sampling step.
