Data:

A randomly selected group of 35 adult American men (subscript M) was asked if they owned a handgun. 20 said yes. A randomly selected group of 40 adult American women (subscript W) was asked if they owned handgun. 21 said yes. Test the claim that the proportion of adult men who own handguns is the same as the proportion of adult women who own handguns. Use α = .05 .
