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 σ = 3.6 pg Fe/mL. If σ is a good estimate of σ, calculate the 95% and 99% confidence intervals for the result 18.5 μg Fe/mL if it was based on (a) a single analysis, (b) the mean of two analyses, and the mean of four analyses.
