Part 1. Construct one table that inckudes relative frequencies based on the frequency distributions shown below, then compare the amounts of tar in nonfiltered and filtered cigarettes. Do the cigarettes filters appear to be efffective? (Hint: The filters reduce the amount of tar ingested by the smoker.)
Part 2. Do cigarettes filters appear to be effective?
A. No, because the relative frequency of the higher tar classes is hreater for filtered cigarettes.
B. Yes, because the relative frequency of the higher tar classes is greater for nonfiltered cigarettes.
C. No, because the relative frequencies for each are not substantially different.
