Answer: A. The value is a statistic because the 1,502 adults 18 years of age or older are a sample.
Step-by-step 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 <u>69 %</u> 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 (
) 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).
