Before 1918, approximately 55% of the wolves in a region were
male, and 45% were female. However, cattle ranchers in this area
have made a determined effort to exterminate wolves. From 1918 to
the present, approximately 70% of wolves in the region are male,

been greatly reduced. (Round your answers to three decimal
