For each sample, calculate the concentration of each of the metals in the original juice (be sure to take into account any sample preparation steps). Average the triplicate samples together and obtain the standard deviation and % relative standard deviation. Are the concentrations of each of the metals statistically different between the fruit juice types? Use a statistical test to support your assertion. Comparison of differences between statistical means is reviewed in your laboratory manual. For Ca from grape juice and apple juice standard deviation s = 0.312 and %RSD= 3.4%, and s = 0.067 %RSD= 3.0% respectively
