Question

Fish continued to be a major source of essential trace elements including iron (Fe) in human's diet. Tilapia fish samples were submitted to two analytical laboratories for Fe analysis, using atomic absorption spectroscopy. The results of the fish Fe analysis obtained by the two laboratories are as follows: lab A: 178 ppm, 180 ppm, 185 ppm, 186 ppm, 179 ppm, 182 ppm Lab B: 165 ppm, 170 ppm, 180 ppm, 168 ppm, 167 ppm, 169, 186ppm, Assuming the "true value" of Fe concentration in the fish is 180 ppm, which result is the most accurate data? Is there any significant difference in the reproducibility of the results of the two laboratories? Is there any significant different in the result of Lab B and the "true value" at 98% confidence interval? The result of 186 ppm obtained by lab B tor Fe analysis is questionable Using a Grub test, must this data be kept or rejected?

Explanation / Answer

Answer C: No there is no significatnt in the result of Lab-B

Answer D: Well it is questionale but the main caused should be focused as the result indicates the qualitative and quantitive analysis but the Fe ie iron content deficiency in human diet. So the data can be kept for future references and if still there is doubt you can check it again.
