Final answer:
The term 'parameter' refers to a measure that describes an entire population, while 'statistic' refers to a measure from a sample of the population. For a population of 85,000 people, surveying all 85,000 members would result in a parameter. Thus, the correct answer is D. 85,000.
Step-by-step explanation:
The question presented asks about the difference between a parameter and a statistic. A parameter is a summary measure that describes a characteristic of an entire population. On the other hand, a statistic is a summary measure that describes a characteristic of a sample taken from the population. With a population of 85,000 people, if all 85,000 are surveyed, the resulting figure would represent a parameter because it encompasses the entire population.
Therefore, the correct answer to the question is D. 85,000, since this is the only option that refers to the total population, and thus would yield a parameter rather than a statistic.
