The data in the accompanying table are from an experiment seeking to determine why some male fish attract more females than others. A scientist scored females' preference for particular males from 0 (low) to 3 (high), the number of zig-zag courtship dances the males did for each female, and the intensity of the color of the male's throat, a trait that generally indicates sexual maturity. Which hypothesis is supported by the data in the table?
◦ Females prefer males that spend little time in courtship.
◦ Males generally spend more time courting females that show an interest in them (demonstrate a preference).
◦ The redness of a male's throat predicts how much a female is likely to prefer him.
◦ Male fish spend less than a minute courting females that do show a preference toward them.
