Parameter or statistic??

Florida played a key role in recent presidential elections. Voter registration records in February 2014 show that 39% of Florida voters are registered as Democrats and 35% as Republicans. (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?

a)The three boldface numbers are statistics.

b) 39% and 35% are statistics and 34% is a parameter.

c) 39% and 35% are parameters and 34% is a statistic.

d) 39% is a parameter, 35% and 34% are statistics.

e) The three boldface numbers are parameters.
