Phade,
I did just buy "The Deer of North America" by Leonard Lee Rue and on page 250 he discusses the ratios of the sex of fawns. He suggests that sex ratios are determined by the quality of the habitat.His ratios were never 50/50, even statically. The swing in higher buck birthing rates or higher doe birthing rates is quite pronounced. Very interesting reading.
I might suggestrereading the information again...In all cases the pendulum swings in the buck/doe fawn ratio's favor bucks in a relative sense.
For example in good conditions the studies you are discussing suggest that the ratio was 43% males and 57% females.
In bad conditions the studies found 72% males and only 28% females.
Notice that good conditions only result in a small decline in buck production. However, in bad conditions the ratio of buck to doe fawns explodes signifactly higher.
As far as the statistical discussion is concerned, Phade is correct on that one...
