Accepted Solution

A:
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 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 ([tex]\hat{p}[/tex]) 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).
