The concentrations of K+ in water were measured with atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES). Four water samples obtained at different cities were used, and each sample was measured one time. The measurements are shown in the table below: Fresno Tulare Clovis Selma 12.5 ppm 5.5 ppm 8.9 ppm 6.7 ppm 5.0 ppm 9.8 ppm 5.4 ppm 7.0 ppm What is the calculated t-value (tcalculated) for the statistical comparison of these two methods? AAS AES 1.908 2.664 2.309 2.938 3.012
