A one-sample t-test of the"reverse null" hypothesis asserting that the 2015 BRB-2 total allowable <br /> herbaceous production (transformed data) is indistinguishable from the weighted average <br /> Reference Area allowable herbaceous production (transformed data) is as follows (transformed <br /> data are square roots of oven-dry gm/0.5sq.m. data): <br /> aF- (0.9 : technical standard) <br /> U71) <br /> t_calc = (40.2 — 24.5)/(9.7/Q3Q110.5 ) = 8.865 <br /> Since critical ttabie = 0.854 (one-tailed, alpha = 0.2, 30-1 df) is exceeded by Laic (8.865), the <br /> hypothesis of no difference is rejected and reclamation success for 2015 BRB-2 Phase III <br /> production is demonstrated. <br /> 2016 Production Success Evaluation <br /> Calculation of 90 percent of the production performance standard relative to 2016 sample data is <br /> demonstrated below. <br /> Aspen Reference Area Allowable Herbaceous Production' = 985.1 lbs/acre <br /> Mountain Brush Reference Area Allowable Herbaceous Production' =494.2 lbs/acre <br /> Sagebrush Reference Area Allowable Herbaceous Production' = 1046.1 lbs/acre <br /> Steep Mountain Brush Reference Area Allowable Herbaceous Production' = 532.4 lbs/acre <br /> 'Herbaceous production adjusted by subtracting annual/biennial plant production in excess of IO%of the remainder. <br /> Production by noxious weed species is not collected. <br /> 90 percent of the 2016 production standard= <br /> 0.90 [0.244(985.1)+0.489(494.2)+0.240(1,046.1)+0.027(532.4) = 672.7 lbs/acre <br /> As can be seen, the 2016 BRB-2 mean allowable herbaceous production of 1,873.8 pounds per <br /> acre (Table 7) far exceeded 90 percent of the production performance standard of 672.7 lbs/acre. <br /> The average herbaceous production by annuals and biennials sampled in the BRB-2 was less than <br /> 10% of total herbaceous production (51.2 lbs/acre non-noxious annuals and biennials).
