The amount of ascorbic acid in cashew juice of different brands was determined by two different methods, colorimetry and titrometry. The results obtained for the two methods for analyzing the different cashew juice are necessary in the following table. Sample Colorimetry (mg/100g) Titrometry (mg/100g) juice brand A 152,2 153,7 juice brand B 150,7 150,7 juice brand C 18,7 18,7 juice brand D 67,4 67,4 Can the two methods be used, indistinctly, to determine ascorbic acid in cashew juice, at a 95% confidence level? Explain.
