Normality test: Shapiro Wilk @alpha = 0.01, calculated = 0.9101, critical =0.904. Report alpha= 0.05. Rosnees Outlier Test was performed on the background data. Two background outliers were removed: 240 (5/13/2004); 13 (8/142007).

Most recent observation is compared with limn. Limit is highest of 34 background values. 94.12% NDs. 87.3% coverage at alpha=0.01: 91.6% coverage at alpha=0.05: 97.85% coverage at alpha=0.5. Report alpha = 0.1748. After outlier removal distribution was non -normal, so outlier results were invalidated.
