The State Center for Health Statistics for the North Carolina Division of Public Health released a report in 2010 that indicates that there are racial disparities in colorectal cancer incidence and mortality rates. The report states, “African Americans are less likely to receive appropriate screenings that reduce the risk of developing or dying from colorectal cancer.” During 2002–2006, the rate of incidence for African Americans was 57.3 per 100,000 versus 46.5 per 100,000 for White residents. African Americans were 19% more likely to have been diagnosed with colon cancer. Explain how to get this estimate.
