A researcher is investigating the physical characteristics that influence whether a person's face is judged as beautiful. The researcher selects a photograph of a woman and then creates two modifications of the photo by (1) moving the eyes slightly farther apart and (2) moving the eyes slightly closer together. The original photograph and the two modifications are then shown to a sample of n = 150 college students, and each student is asked to select the "most beautiful" of the three faces. The distribution of responses was as follows: Original Photo Eyes Moved Apart Eyes Moved Together 51 72 27 Do the data indicate any significant preferences among the three versions of the photograph?
