I need help getting started on this question: Is our system of justice colorblind in the administration of the death penalty?

Here is the data given to us (Numbers like 422, 99, etc. represent the number of cases):

DEATH Black White
SENTENCES Victim Victim Total

Black
Defendants: 76 of 422 21 of 99 97 of 521

White
Defendants: 1 of 25 17 of 121 18 of 146

Total: 77 of 447 38 of 220 115 of 667
