The concentration of metals was calculated from linear regression graph and found to be Ca: =183.3 Mg = 177.5, Na= 124.0, and K = 679.2 in mg/mL. and the original concentration from the grape juice is Ca = 120, Na =80, K = 600, and Mg = 50.8. the t- value is 62.16. Are the concentrations of each of the metals statistically different between the fruit juice types? Use a statistical test to support your assertion.
