H-G needs to provide a statistical analysis for all comparisons <br />between reference areas and premining areas. This should be a t-test <br />and should provide the level of significance achieved for each parameter. <br />6. Furthermore, if H-C is sampling their reference areas such that <br />n/N ~ .OS (where n is the number of samples taken and N is the total <br />number of samples available in the reference area), they must include <br />a finite population correction factor (1-n/N) in all of their associated <br />calculations. <br />
