14.12 Twenty married couples were selected at random from a large population and each person was asked privately whether the family would prefer to spend a week’s summer vacation at the beach or in the mountains. The subjects were told to ignore factors such as relative cost and distance so that their preference would reflect only their expected pleasure from each type of vacation. The husband voted for the beach seven times and his wife agreed four times. The husband voted for the mountains 13 times and his wife agreed five times.

Determine whether family vacation preference is dominated by the husband.
