Answer 1

Answer: A. The value is a statistic because the 1,502 adults 18 years of age or older are a sample.

Explanation:

A parameter is a number that represents a characteristic for a whole population whereas a statistic is a number that represents a characteristic from a a subset of population which is known as sample.

Given : Telephone interviews of 1,502 adults 18 years of age or older found that only 69 % could identify the current vice president.

Since, 1,502 is a very small number compare to the population in a particular country.

It means 1,502 represents a sample from the population.

Thus, 69% represent the sample proportion (
`\hat{p}`) of adults 18 years of age or older could identify the current vice president.

Hence, 69% is a statistic because the 1,502 adults 18 years of age or older are a sample.

Thus , the correct answer is option (A).
