A survey on the background concentration of lead in soil was conducted in an Environmental Impact Assessment of a former battery plant. Preliminary results of six soil samples in the protected area give results in mg/kg: 28, 32, 21, 29, 25, 22. (a) Is there any value in this data set that can be discarded as an outlier at 90% confidence level? (b) Calculate CV, RSD, and 95% Confidence Interval (CI)?
Soil samples were collected at two areas surrounding an abandoned mine and analyzed for lead. At each area several samples were taken. The soil was extracted with acid, and the extract was analyzed using flame atomic absorption spectrometry. In Area A, Pb concentrations were 1.2, 1.0, 0.9, 1.4 mg/kg. In Area B, Pb concentrations were 0.7, 1.0, 0.5, 0.6, 0.4 mg/kg. Are these two areas significantly different from each other with Pb concentrations at 90% confidence level?
