Some people feel that they have good intuition about when others are lying, while others do not feel they have this ability. Are the more "intui- tive" people better able to detect lies? Each of 100 people who thought they had good intuitive abilities was shown a video clip of a person stat- ing the name of his or her favorite movie (Young 2002). The person was truthful in some of the clips shown, whereas in others the person was lying. Another 100 people who claimed not to bave intuitive abilities were shown similar video clips. Fifty-nine of the 100 "intuitive" subjects correctly identified whether the person in the video was lying, whereas 69 of the 100 "nonin- tuitive" subjects correctly identified whether the person in the video was lying. a. Draw a graph that best presents these data. What association is suggested? b. Test whether the success rates of the two groups were different. c. Are "intuitive" people better at detecting lies than "nonintuitive" people? Calculate an odds ratio and confidence interval for your answer, Interpret your result.
