67% is a statistic and 81% is a parameter.

#### Explanation:

A statistic tries to estimate something about the population- in this case, the statistic is estimating the percentage of registered voters that vote in the election. A parameter is the value that the statistic is trying to estimate- the actual percentage of registered voter support that showed up on Election Day.
