章节摘录

版权页：   插图：   Example 7.5 Exit Polls （see Chapter 7） When an election for political office takes place， the television networks cancel regular programming and provide election coverage instead. When the ballots are counted， the results are reported. However， for important offices such as president or senator in large states， the networks actively compete to see which will be the first to predict a winner. This is done through exit polls， wherein a random sample of voters who exit the polling booth is asked for whom they voted. From the data the sample proportion ofvoters supporting the candidates is computed. A statistical technique is applied to determine whether there is enough evidence to infer that the leading candidate will garner enough votes to win. Suppose that the exit poll results from the state of Florida during the 2000 year elections were recorded.Although there were a number of candidates running for president， the exit pollsters recorded only the votes of the two candidates who had any chance of winning， the Republican candidate George W. Bush and the Democrat Albert Gore. The results （765 people who voted for either Bush or Gore） were stored on a file on the disk. The network analysts would like to know whether they can conclude that George W. Bush will win the state of Florida. Example 7.5 describes a very common application of statistical inference. The population the television networks wanted to make inferences about is the approximately 5 million Floridians who voted for Bush or Gore for president.The sample consisted of the 765 people randomly selected by the polling company who voted for either of the two main candidates. The characteristic of the population that we would like to know is the proportion of the Florida total electorate that voted for Bush. Specifically， we would like to know whether more than 50% of the electorate voted for Bush （counting only those who voted for either the Republican or Democratic candidate）. It must be made clear that， because we will not ask every one of the 5 million actual voters for whom they voted， we cannot predict the outcome with 100% certainty. This is a fact that statistics practitioners and even students of statistics must understand. A sample that is only a small fraction of the size of the population can lead to correct inferences only a certain percentage'of the time. You will find that statistics practitioners can control that fraction and usually set it between 90% and 99%.
