Chemistry Question

I need help with part c, thank you!

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 Clovis 8.9 ppm 6.7 ppm 7.0 ppm 5.0 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 Selma 12.5 ppm 9.8 ppm

I need help on this?

Please help me find volume 285m^3 in each of these unit's with work! Thanks so much
