allowable herbaceous foliar cover were above 90% of the reference area-derived standard, an <br />• affirmative indication of reclamation cover success was to be asserted. <br />If: The mean allowable herbaceous cover of an adequate sample from Phase II Bond Release <br />Area was less than 90% of the cover standard (see above), then a one-sample t-test was to be <br />made in the following form to test the hypothesis of reclamation success for cover (CDMG rules, <br />4.15.11 (2)(b)): <br />t _Q-x <br />S- <br />x <br />Where: <br />x = Bond Release Block Sample Mean <br />Q = 90% of Standard <br />] <br />S- = Standard error of mean [ s l Fn <br />X <br />s = Sample standard deviation <br />n = Sample size <br />tc = Calculated t value <br />• tt = Table t value <br />The null hypothesis being tested was that the bond release block mean (µ) was greater than or <br />equal to 90% of the standard, stated as Ho: µ >_ Q. If tc was less than or equal to the 1-tailed t <br />table value for alpha error probability of 0.10, at (n-1) degrees of freedom (infinite degrees of <br />freedom may be used if n>30), then Ho was not rejected, and revegetation was deemed <br />successful for the parameter tested. <br />If: Sample adequacy for herbaceous cover has not been achieved in Phase II Bond Release <br />Area and a total of 30 or more samples have been taken, and the means for total allowable <br />herbaceous foliar cover in the Phase II Bond Release Area exceed 90% of the reference area- <br />derived standard, then the hypothesis of reclamation success is tested under the conditions of a <br />"reverse null" approach using a parametric test of the "reverse null" hypothesis. This would be <br />conducted using the following expression (CDMG rules, 4.15.11 (2)(c)): <br />x-Q <br />tc _ <br />S- <br />x <br />• Where: <br />X = Bond Release Block Sample Mean <br />6
