In 1981 a study on race and the death penalty was released. The data in Figure 3.52 are from that study.
Death penalty imposed? | Victim’s race | Defendant’s race |
Frequency |
Yes | White | White | 19 |
Yes | White | Black | 11 |
Yes | Black | White | 0 |
Yes | Black | Black | 6 |
No | White | White | 132 |
No | White | Black | 152 |
No | Black | White | 9 |

- Find all solutions of the polynomial congruence x²+4x+1 = 0 (mod 143). (The solutions of the congruence x² + 4x+1=0 (mod 11) are x = 3,4 (mod 11) and the solutions of the congruence x² +4x+1 = 0 (mod 13) are x = 2,7 (mod 13).)arrow_forwardhttps://www.hawkeslearning.com/Statistics/dbs2/datasets.htmlarrow_forwardDetermine whether each function is an injection and determine whether each is a surjection.The notation Z_(n) refers to the set {0,1,2,...,n-1}.
