We often judge other people by their faces. It appears that some people judge candidates for elected office by their faces. Psychologists showed head-and-shoulders photos of the two main candidates in 36
races for the U. S. Senate to many subjects (dropping subjects who recognized one or both of the
candidates) to see which candidate was rated "more competent" based on nothing but the photos. On
election day, the candidate whose face looked more competent won 22 of the 36 contests. If faces don't
influence voting, half of all races in the long run should be won by the candidate with the better face.
Is there evidence that the candidate with the better face wins more than half the time? Carry out an
appropriate test to help answer this question.
