As a data collection specialist at the National Institutes of Health( NIH), you have been involved in a research study conducted over the past year. The study found that liver cancer rates per 100,000 males among cigaretted smokers versus nonsmokers, in a major U.S. city were 48.0 to 25.54, respectively.

1. In view of these data, calculate the relative risk of males in developing liver cancer, for smokers as compared to nonsmokers ( round to two decimal places). Show your work.

1. Develop a pie chart to display the risks among the 2 groups presented. Include characteristics of good graph display with appropriate lables and title.
