In Exercise B.40, we learn that when 48 stressed individuals read a truthful passage while being hooked up to a lie detector, the lie detection software inaccurately reported deception by 27 of them. Does this sample provide evidence that lie detection software will give inaccurate results more than half the time when used in situations such as this? State the null and alternative hypotheses. Use StatKey or other technology to create a randomization distribution, find a p-value, and give a clear conclusion in context.  

Exercise B.40

Is lie detection software accurate? A recent study was conducted in order to test the accuracy of a commonly used method of lie detection. The researchers are specifically interested in how lie detectors perform when an individual is stressed. A sample of 48 participants were gathered and attached to the lie detection device. They were asked to read deceptive material out loud while receiving an electric shock (to add stress). The lie detector failed to report deception in 17 of the 48 participants.
