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. Frequency Distributions Complete the relative frequency table below. Tar (mg) in Tar (mg) in Relative Relative Nonfiltered Filtered Frequency Frequency Cigarettes Frequency Cigarettes Frequency Tar (mg) (Nonfiltered) (Filtered) 12 - 15 4-7 3 ON 4-7 % % 16 -19 8 - 11 20 -23 14 12 - 15 8-11 % % 24-27 8 16- 19 14 12 - 15 28 -31 16 -19 % % 20 - 23 % 1% 24-27 0% % 28 -31 % % Print Done (Simplify your answers.) Do cigarette filters appear to be effective? O A. No, because the relative frequency of the higher tar classes is greater for filtered cigarettes. O B. No, because the relative frequencies for each are not substantially different. O C. Yes, because the relative frequency of the higher tar classes is greater for nonfiltered cigarettes. O D. This cannot be determined
