Ou administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. you then have your subjects complete a simulated driving task in which the drivers must follow a fixed speed limit while driving on a straight road. wind periodically and randomly pushes the simulated vehicle right, left, or not at all. motor control is measured in terms of the number of feet the car moves from the center of the driving lane, with 1 foot being the smallest unit on the scale. suppose the first subject scores 15 feet. determine the real limits of 15.
