An environmental scientist developed a new analytical

Question- An environmental scientist developed a new analytical method for the determination of cadmium (Cd2) in mussels. To validate the method, the researcher measured the Cd2 concentration in standard reference material (SRM) 2976 that is known to contain 0.82 Â± 0.16 ppm Cd2. Five replicate measurements of the SRM were obtained using the new method, giving values of 0.794, 0.761, 0.826, 0.845, and 0.776 ppm Cd2.
