It is not certain, as we have only fossilized bones which tell us little about dinosaurs' soft tissues and organs which we would need to determine warm-/cold-bloodedness, but generally assumed that dinosaurs were, like modern reptiles, cold-blooded. However, it has been recently discovered that at least some dinosaurs had live births, which is very surprising because it is most definitely not a trait of modern reptiles (modern reptiles lay eggs that hatch and do not have live births); this may lead to increased doubt over whether dinosaurs had many traits in common with modern reptiles, including being cold-blooded. Two groups of warm-blooded animals, mammals and birds, are descended from dinosaurs.
In 2008, 80 infants died per 1000 live births.
The overall ratio of live births worldwide is about 1.01 births for boys to 1.0 for girls. That has been the ratio since records have been kept.
