Prints link with gay sexuality

Assuming that 22 of the 66 homosexual men (1/3) and 26 of 182 heterosexual men (14%) had more ridges in the left hand than the right, it is possible to do a hypothesis test on the difference in proportions and it is indeed statistically significant. Several questions, however, arise from this research. Since there is a much higher percentage of heterosexual men than homosexual men in the community, there will in practice be (like in the sample) more heterosexual men than homosexual men with the characteristic. This severely limits the usefulness of the information for diagnostic purposes.
