This Question from Practical Nonparametric Statistics

A traffic study was conducted for a short time on a well-traveled city street. Of the 64 cars observed, 16 were exceeding the limit and 48 were not. Also, 24 of the drivers had a passengers and the rest did not. Twelve of the speeders were driving alone. Assume that the observed traffic behaves the same as a random sample of all traffic would. use R5 to see if there is a positive correlation between speeding and driving alone.
