Polling agencies claim to provide accurate readings of the pulse of America. They give the public a percentage of the population who are likely to vote for a particular candidate, or a company the probability that their customers may purchase their product. Polling organizations sample the population and use a proportion to predict the results during an election or the likelihood a customer will buy. Choose a polling organization and look up a current sampling situation. Discuss the poll, sample size, point-estimate, margin of error, and inferences. Explain the importance of this data and what you find interesting about the results. Be sure to provide a reference to your poll.
