- Construct one table that includes relative frequencies based on the frequency distributions shown below, then compare the amounts of tar in nonfiltered and filtered cigarettes. Do the cigarette filters appear to be effective? (Hint: The filters reduce the amount of tar ingested by the smoker.) Click the icon to view the frequency distributions.

- Construct one table that includes relative frequencies based on the frequency distributions shown below, then compare the amounts of tar in nonfiltered and filtered cigarettes effective? (Hint: The filters reduce the amount of tar ingested by the smoker.) Click the icon to view the frequency distributions. ..... Complete the relative frequency table below.

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