Is the amount of violent crime related to what police officers are paid? The U.S. Bureau of Labor Statistics publishes data on occupational employment and wage estimates (www.bls.gov/oes/) for each of the 50 states. Here are data released from 2011 to 2013.
The variables are:

Violent Crime (crimes per 100,000 population)
Police Officer Wage (mean $/hr)
Graduation Rate (%)
One natural question to ask of these data is how police officer wages are related to violent crime across these states.
First, here are plots and background information.
a) Name and check (to the extent possible) the regression assumptions and their corresponding conditions.
b) If we found a regression to predict Violent Crime just from Police Officer Wage, what would the R2 of that regression be?
