Most recent observation is compared with limit. Background Data Summary (based on cube root transformation): Mean=1.21, Std. Dev.=0.2264, n=32. Normality test: Shapiro Wilk @alpha = 0.01, calculated = 0.9157, critical= 0.904. Report alpha= 0.05. The EPA 1989 Outlier Test was performed on the background data. No background outliers were found. ,92.17 nM. UG Within Limit 70 56 42 E ,92.17 nh.

UG Tolerance Limit Within Limit Tolerance Limit Interwel Non -parametric Irderwel Parametric MMMMM MMMMM MMMMM mmmm Limit = 43 2/13/97 4/15/00 6/17/03 8/17/06 10/18/09 12/19/12 Non -parametric lest used in lieu of parametric tolerance limit because the Shapiro Wilk normality test showed the data to be non -normal at the 0.01 alpha level. Most recent observation is compared with limit. Limit is highest of 46 background values. 90.43% coverage at alpha=0.01; 93.55% coverage at alpha=0.05; 98.63% coverage at alpha=0.5. Report alpha = 0.09447. After outlier removal distribution was non -normal, so outlier results were invalidated.
