Question
Ruth and her colleagues developed a spectrophotometric method for the determination of Fe3 + in biological samples. As part of their study, the concentration of Fe3 + in human serum samples was determined using their new method and the standard method of AOOC. The results obtained with both methods, in concentrations ?mol / L, are shown in the following table: Determine if there is a significant difference between the averages and the accuracy of the two methods at ? = 0.05. Show all your calculations and reasoning to receive credit.
