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: Tulare 8.9 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 Fresno 5.5 ppm 5.4 ppm Clovis 6.7 ppm 5.0 ppm Selma 12.5 ppm 9.8 ppm
