Determine whether the underlined value is a parameter or a statistic. Telephone interviews of 1,502 adults 18 years of age or older found that only 69% could identify the current vice-president. Is the value a parameter or a statistic? OA. The value is a statistic because the 1,502 adults 18 years of age or older are a population. B. The value is a parameter because the 1,502 adults 18 years of age or older are a population. C. The value is a statistic because the 1,502 adults 18 years of age or older are a sample. OD. The value is a parameter because the 1,502 adults 18 years of age or older are a sample.
