A professional sports team
traded its best player. The local
television station wanted to
find out what the fans thought
of the trade. At the beginning
of the evening news program,
they asked viewers to call one
number if they favored the
trade and a different number if
they were opposed to the
trade. At the end of the news
program, they announced that
52.7% of the callers favored
the trade.
