Studies have found that people find symmetrical faces more attractive than faces that are not symmetrical. To test this theory, a psychiatrist selected a random sample of people and showed them pictures of three different faces: a face that is perfectly symmetrical, a face that is slightly asymmetrical, and a face that is highly asymmetrical. She then asked them to rate the three faces in terms of their attractiveness on a scale from 1 to 7, with 7 being the most attractive. Test the null hypothesis that attractiveness does not differ with facial symmetry.
