Chapter 10, Problem 74CRE

Conviction Rate with Opposite Race Here are the conviction rates with the “stand your ground” data mentioned in the previous exercise. “White shooter on nonwhite” means that a white assailant shot a minority victim.

a. Which has the higher conviction rate: white shooter on nonwhite or nonwhite shooter on white?

b. Create a two-way table using White Shooter on Nonwhite and Non-White Shooter on White across the top and Convicted and Not Convicted on the side.

c. Test the hypothesis that race and conviction rate (for these two groups) are independent at the $0.05$ level.

d. Because some of the expected counts are pretty low, try a Fisher’s Exact Test with the data, reporting the $\text{p-value}$ (two-tailed) and the conclusion.
