suppose a population consists of 8500 people. which of the following numbers of members of the population being surveyed could result in a parameter but not a sample statistic?A. both 85 and 8500B. 85C. neither 85 nor 8500D. 8500HELP PLEASEE!!

Sagot :

Let's recall what are the differences between parameter and statistic:

Parameter is a descriptive measure calculated from an entire population of data.

Statistic on the other hand, is a descriptive measure calculated from a sample of data.

Upon saying that,

8,500 is a parameter because it is the entire population. So a survey with 8,500 people is not a statistic, it is a parameter.

On the other hand, 85 is a small sample that you can use for the survey and actually it is just the 1% of the total population and we're confident that this is a statistic, not a parameter.

Therefore, the correct answer is:

D. 8,500
