reclamation success for Phase III is demonstrated by passing a one sample t-test of the "reverse <br />null" hypothesis (CDMG 2005 revised rule, 4.15.11 (2)(c)). The 2012 BRB-1 production data <br />were first evaluated for normality of distribution using the Shapiro-Francia test (Table 1 and <br />accompanying discussion, Page 26 of the Vegetation Report contained in Attachment D). This <br />test was not passed. Following a square root transformation of the data, the test was passed. <br />Hypothesis testing was conducted using square root transformed data for both the BRB-1 <br />production data and the production technical standard. <br />A one -sample t-test of the "reverse null" hypothesis asserting that the 2012 BRB-1 total <br />allowable herbaceous production (transformed data) is indistinguishable from the weighted <br />average Reference Area allowable herbaceous production (transformed data) is as follows <br />(transformed data are square roots of oven -dry gm/0.5sq.m. data): <br />7— (0.9 s technical standard) <br />tGair = <br />S <br />12 <br />t 7.315 — 4.451 —5.320 <br />Gate `-13=5 <br />85 <br />-) <br />Since critical ttable = 0.852 (one -tailed, alpha = 0.2, 35-1 df) is exceeded by tcalc (5.320), the <br />hypothesis of no difference is rejected and reclamation success for 2012 BRB-1 Phase III <br />production is demonstrated. <br />2014 Production Success Evaluation . <br />Calculation of 90 percent of the production performance standard relative to 2014 sample data is <br />demonstrated below. <br />Aspen Reference Area Allowable Herbaceous Production) = 1525.6 lbs/acre <br />Mountain Brush Reference Area Allowable Herbaceous Production) = 778.0 lbs/acre <br />Sagebrush Reference Area Allowable Herbaceous Production) = 833.61bs/acre <br />Steep Mountain Brush Reference Area Allowable Herbaceous Production' = 627.5 lbs/acre <br />SL -6 - 15 <br />
