Strayer, Drews, & Couch (2006) ran a study in which they compared the driving behavior of a control group, a group that was at the legal limit for alcohol, and a group that was talking on a cell phone. I have modified their study slightly to make it suitable for this chapter, but the results are consistent with theirs. The three groups are given below (the data are available on the Web site for this book at Ex11-32.dat).

Control:

How does the cell phone condition differ from the alcohol-impaired condition?
