1) If sample adequacy exists at the reclaimed site and the reference area, and the reclaimed site <br />mean is equal to or greater than Q, no statistical comparison is necessary and revegetation at the <br />reclaimed site will be deemed successful for the parameter in question. This complies with the <br />provisions of DRMS Regulation 4.15.11(2)(a). <br />2) If sample adequacy exists at the reclaimed site and the reference area, and the mean value at <br />the reclaimed site is less than Q, a "standard null' one -sided t -test with alpha error probability of <br />0.10 will be used, in conformance with DRMS Regulation 4.15.11(2)(b), using the general form <br />of the one -sided t -test as follows: <br />c <br />S X <br />Where: <br />x = Bond Release Block Sample Mean <br />Q = 90 % of Standard <br />S- = Standard error of mean [ s / % n ] <br />S = Sample standard deviation <br />n = Sample size <br />t, = Calculated t value <br />t, = Table t value <br />The null hypothesis being tested is that the mean value at the reclaimed site is greater than or <br />equal to Q, with 90% statistical confidence. If t is less than or equal to the 1- tailed t table value <br />PR -06 June 2010 2.05.4(2)(e) - 59 <br />
