(Most of the others did not choose a party.) To test a random digit dialing device that you plan to use to poll voters for the 2014 Senate elections, you use it to call 250 randomly chosen residential telephones in Florida. Of the registered voters contacted, 34% are registered Democrats. Is each of the boldface numbers a parameter or a statistic?
