An atomic absorption method for the determination of the amount of iron present in used jet engine oil was found from pooling 30 triplicate analyses to have a standard deviation s = 3.8 µg Fe/mL. How many replicate measurements are needed to decrease the 95 and 99% confidence limits to ± 2.1 µg Fe/mL? (This problem requires values in your textbook's specific appendices, which you can access through the OWLV2 MindTap Reader. You should not use the OWLV2 References' Tables to answer this question as the values will not match.) For a 95% confidence limit, N=[ For a 99% confidence limit, N=|
