Explanation:

Question #6

To get an unbiased sample for surveying Trump's approval among registered voters in Aston, PA, the sample should represent all registered voters in Aston. Options A (students), B (faculty), and C (alumni) of Neumann University are subsets of the population and may not represent all registered voters. Option D is Aston residents who are registered to vote, which directly targets the population of interest (registered voters in Aston), so it's the most likely to be unbiased.

Descriptive statistics summarizes or describes a population's characteristics. Inferential statistics makes inferences about a population from a sample. The claim "The average age of all voters in the U.S.A. is 55 years" describes a characteristic (average age) of the entire population of U.S. voters, so it's descriptive statistics.

Answer:

D. Aston residents who are registered to vote in November
