Question

You want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, fo lowed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicde right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 9 mph. Determine the real limits of 9. The lower real limit is: The upper real limit is: When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 120 pounds? O 119.75-120.25 O 120-121 O 119.9-120.1 When measuring weight on a scale that is accurate to the nearest o.5 pound, what are the real limits for the weight of 187 pounds? O 187-188 O 186.75-187.25 O 186.95-187.05
