The Traffic Court of King James County operates between the hours of 9 A. M. and 1 P. M. Each morning, roughly at 9 p. m., 200 defendants show up for trial involving traffic violations, such as speeding, illegal parking, and ignoring a stop sign. On Monday, June 10, 2003, a sample of 10 defendants was selected at random by a consultant. For each defendant, the consult-ant recorded the actual time spent in discussion with the judge and the time paying the fine (not including waiting). Also recorded were the times the defendant arrived and left the court. The data are summarized in Table 4.7.
