Is the perception of eye-gazing in humans acquired through experience, or is it innate? To test this, Farroni et al. (2002) presented 17 infants (3–5 days old) with paired photographs of faces. The face in one photograph had a direct gaze, whereas the other had an averted gaze (see image). Fifteen of 17 infants spent more time gazing at the face with the direct gaze. Use the log-likelihood ratio test to test the null hypothesis of no preference. Show the
steps of your calculations.
