An environmental scientist developed a new analytical method for the determination of cadmium (Cd 2+) in mussels. To validate the method, the researcher measured the Cd2+ concentration in standard reference material (SRM) 2976 that is known to contain 0.820.16ppmCd2+. Five replicate measurements of the SRM were obtained using the new method, giving values of 0.799, 0.753,0.822,0.841, and 0.763ppmCd2+. Calculate the mean (x), standard deviation (sx), and the 95% confidence interval. A list of t values can be found in the Student's t table. sx= ppm 95% confidence interval: ppm Does the new method give a result that differs from the known result of the SRM at the 95% confidence level? no
