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 65% of wolves in the region are
male, and 35% are female. Biologists suspect that male wolves are more likely than females to return to an area where the
population has been greatly reduced. (Round your answers to three decimal places.)
