From: Homologue distribution patterns of 2,3,7,8-chloro-substituted PCDD/F in Bavarian soils

	lcH			hcH
	F versus C	F versus G	C versus G	F versus C	F versus G	C versus G
H	H₁	H₁	H₁ (H₀)*	H₁	H₁	H₁ (H₀)*

H: Hypothesis (α = 0.05); H₀: Samples belonging to same population; H₁: Samples deriving from diverse population
