In Problems 27–30, (a) construct a histogram for the data using the given number of classes to show that the data are approximately
27. A researcher is studying reaction times in adult subjects that are alcohol-impaired in an effort to study the effects of impairment on driving. The amount of time 25 randomly selected adults lake to react to a stimulus when they have a blood alcohol level of 0.08 was recorded and is displayed below, Use live classes; find the probability that a randomly selected driver with a blood alcohol of 0.08 will take less than 1.5 seconds to react, and the probability that he or she will take between 2 and 4 seconds to react.
