Explanation of Solution

Given:

    Calibres of gun Buyback Homicide
    Small (.22, .25, .32) 76.4% 20.3%
    Medium (0.357, 0.38, 9mm) 19.3% 54.7%
    Large (0.40, 0.44, 0.45) 2.1% 10.8%
    Other 2.2% 14.2T

76.4% of the handguns are there in the buyback program are small calibers where only 20.3% of those involved in the homicides are small caliber. A disparity could exist in every category- with 19.3% of the handguns are there in the homicides is medium caliber. In addition, 2.1% of the handguns from the buyback program are large caliber where 10.8% of the handguns in the homicides are large caliber. Lastly, 2.2% of the handguns in the buyback program are “other” caliber where 14.2% of those in homicides are “other” caliber.
