Answer:
Population.
Explanation:
Given the extent of the research, the most accurate answer would be a population. A sample would be a small or quantity intended to show what the whole is like. A statistic would be the piece of data obtained from numerical data. And, last but not least, a parameter, which sets the conditions of the operation, how it is measurable. In this case, to take an average, which is different from a statistic, leaves these options out. But, all in all, what the researcher is curios about is to take an average out of the registered voters in Florida.
