You can check the infant mortality rate of male and female babies on cia worldbook website.
I was also involved in collecting data at the john hopkins on the infant mortality rate and it was seen that female babies have a higher chance of living than male babies for unexplainable reasons

for qatar from cia website

total: 17.46 deaths/1,000 live births
male: 20.6 deaths/1,000 live births
female: 14.16 deaths/1,000 live births (2007 est.)
