For a sampling and analysis method seven sample blanks are collected, as specified by the EPA method. The samples are analyzed for benzene content and the resulting data, in ppb, are: 0.001, 0.002, 0.005, 0.009, 0.011, 0.011, and 0.020. Calculate the mean and standard deviation (specify your formula), and define The method detection limit (MDL) as ppb and the method quantification limit (MQL) as ppb

What would s field sample with a measured value of 0.01 ppb would be reported as on the analysis report, and what would a field sample with a measured value of 0.04 ppb would be reported as on the analysis report.

A field sample with a measured value of 0.09 ppb would be reported as _______________________ on the analysis report
