An article in Cosmo reported that the average man has sex with 12 women
before death, the average woman has sex with 3 men before death. Is this
statistically possible? My girlfriend claims it is so, but her examples
fall apart with a bit of scrutiny. The average for both groups changes by
the same factor every time two people have sex. She then says it is due to
an uneven population, but I argue that the population would have to be a
whole hell of a lot more disproportionate for a ratio like 4:1. I think it
is more likely that both groups lied on the survey, women reported lower
numbers and men reported higher numbers.

I guess that the "average man" does not have the average number of sex
partners. The average man would be the median man: half of the men had sex with
12 women of more, half had sex with 11 or less.
That's often what is meant by average man. Otherwise, it is not
possible, if you just count the number of first times 2 persons
had sex together: F, then if there are M men and W women, F = 12M,
and F = 3W, so M = 4W, and we know that there is no such disproportion.

If the male heterosexual population is four times smaller than the female one,
it is. I do not deem it is so, though.

A few hints:
i) men's arrogance and women's decence have twisted the figures :-)
ii) the article is talking about the median, not the average
[In that case, half of the woman have an average of more than
21 partners. B....! ;-)]

> My girlfriend claims it is so

Does she suggest you're slightly too much out?
