To illustrate the effects of driving under the influence (DUI)
of alcohol, a police officer brought a DUI simulator to a local
high school. Student reaction time in an emergency was measured
with unimpaired vision and also while wearing a pair of special
goggles to simulate the effects of alcohol on vision. For a random
sample of nine teenagers, the time (in seconds) required to bring
the vehicle to a stop from a speed of 60 miles per hour was...
