Answer:The correct answer is D. 85,000.
In statistics, a parameter refers to a characteristic of an entire population, whereas a sample statistic refers to a characteristic calculated from a sample taken from the population.
Since the population consists of 85,000 people, any characteristic or number based on the entire population (in this case, the entire 85,000 people) would be a parameter. Therefore, 85,000 is an example of a parameter, not a sample statistic.
On the other hand, sample statistics are calculated from a subset of the population (a sample). In this case, neither 850 nor 85,000 would be considered sample statistics because they represent the entire population, not a sample.
