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 ug Fe/mL. If s is a good estimate of o, calculate the 95 and 99% confidence intervals for the result 19.6 ug Fe/mL if it was based on the following criteria. (a) a single analysis 95% confidence interval =  19.6 ± ___   ug Fe/mL 99% confidence interval =  19.6 ±  ___ ug Fe/mL   (b) the mean of two analyses 95% confidence interval =  19.6 ±   ___   ug Fe/mL 99% confidence interval =  19.6 ±   ___   ug Fe/mL (c) the mean of five analyses 95% confidence interval =  19.6 ±   ___   ug Fe/mL 99% confidence interval =  19.6 ±   ___   ug Fe/mL
