Strayer, Drews, and 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, but the results are consistent with theirs. The three groups are given below (the data are available on the Web site for this book as Ex11–32.dat).

From these data is there evidence that cell phones lead to longer reaction times than baseline conditions? How does the cell phone condition differ from the alcohol impaired condition?
