Question
Mizutani and colleagues reported the development of a new method for the analysis of I-malate. As a part of their study, they analyzed a series of beverages using both their method and a standard spectrophotometric method based on a clinical kit to investigate the precision. A summary of their results is shown in Table 2. Determine whether there is a significant difference between the two methods at a 95% significant level.
