Do cigarette filters appear to be effective?
A. No, because the relative frequencies for each are not substantially different.
B. Yes, because the relative frequency of the higher tar classes is greater for nonfiltered cigarettes.
C. No, because the relative frequency of the higher tar classes is greater for filtered cigarettes.
D. This cannot be determined.
