Median of the χ² random variable and fraction of experiments with V79 cells that support the current hypothesis at a level of significans of 5%

n	Median		Fraction
	2	4	2	4
H0	31	35	0/4	1/4
H1	pf	3	pf	4/4
H2	pf	0.7	pf	4/4

n, multiplicity; pf, the models give a perfect fit to any doublet distribution. The value of the χ² random variable has to be above 5.99 for doublets and 9.49 for quartets to give significant deviation between two distributions within the 5% level of significance.
