Question

You want to find out whether caffeine mitigates the effect of alcohol on motor control. To study this, you administer to you subjects a drink that Is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must following a fixed speed limit when driving on a straight road Wind periodically and randomly pushes the simulated venire 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. When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 225 pounds? 225-226 224.9-225.1 224.75-225.25

Explanation / Answer

b)

Limits = Measured +/- Accuracy

Limits = 225+/- 0.2

(225.2,224.8)

c)

Limits = Measured +/- Accuracy

Limits = 131+/- 0.5

(131.2,130.5)
