A newspaper report in August 2002 raised the issue of racial bias in the issuance of speeding tickets. The following facts were noted:
* The following facts were noted: 16% of drivers registered in New Jersey are black.
* Of the 324 speeding tickets issued in one month on a 65-mph section of the New Jersey Turnpike, 25% went to black drivers.
a) Is the percentage of speeding tickets issued to blacks unusually high compared to the state's registration information?
b) Does this prove that racial profiling may be present?
c) What other statistics would you like to know about this situation?
