To Explain: the few words comparing the distributions.

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.
