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 "intuitive" people better able to detect lies? 100 people were shown a video clip of a person stating the name of his or her favorite movie (Young 2002). The person was truthful in only some of the video clips shown. Another group of 100 people who claimed to not have any "intuitive" ability were shown similar video clips. 59 of 100 "intuitive" people correctly identified whether the filmed person was lying, whereas 69 of the 100 "nonintuitive" people correctly identified if the person in the film clips was lying. Observed Frequencies Table Intuitive Nonintuitive Rows Total Detected Lie Did Not Detect Lie Column Totals 59 Detected Lie 41 100 64 Did Not Detect Lie 36 Column Totals 69 Fill in the expected frequecies table (below) based on your knowledge of the observed frequencies (table above). Round answers to whole numbers. Intuitive Nonintuitive Rows Total 100 31 100 64 128 36 72 200 100 128 72 200 Calculate the odds ratio (OR) to decide if intuitive people are more or less intuitive than the non-intuitive. (Round to two decimal places if necessary)
