1 1.2.15 Question Help 1 '- To illustrate the effects of driving under the inuence (DUI) of alcohol, a police ofcer 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 recorded. Complete parts (a) and (b). Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. a Click the icon to view the data table. (a) Whether the student had unimpaired vision or wore goggles rst was randomly selected. Why is this a good idea in designing the experiment? 0 A. This is a good idea in designing the experiment because the sample size is not large enough. 0 B. This is a good idea in designing the experiment because reaction times are different. C) C. This is a good idea in designing the experiment because it controls for any "learning" that may occur in using the simulator.
