Since the 2015 BRB-3 allowable herbaceous production exceeds 90 percent of the production performance standard (Figure C-2, Table C-1), and sample adequacy has not been demonstrated in either the reclaimed or the reference areas, with the exception of the Mountain Brush ERA where sample adequacy was demonstrated, (minimum of 30 samples) (Table C-4), reclamation success for Phase III BRB-3 has been demonstrated by passing a one sample t-test of the "reverse null' hypothesis (CDMG 2005 revised rule, 4.15.11 (2)(c)). The 2015 BRB-3 production data were first evaluated for normality using the Shapiro-Francia test. Based on the 2015 BRB-3 allowable herbaceous production data the normality test was not passed. Consequently a square root transformation was performed and the normality test was passed (Table 2, below). Hypothesis testing calculations went forward using square root transformed data for both the BRB-3 production data and the production technical standard: Table 2.

Mean shown here is the square root mean of the lbs/acre data. A one -sample t-test of the "reverse null' hypothesis of the assertion that the 2015 BRB-3 total allowable herbaceous production (pounds per acre) is indistinguishable from the area weighted average of the Extended Reference Area allowable herbaceous production is as follows: _ a- — (0.9 = technical standard) TCGiC UnO tcaic = (35.6 — 22.7) / (8.425/(32^0.5)) = 8.687 25
