Part 1 and two please

Construct one table that includes relative frequencies based on cigarettes. Do the cigarette filters appear to be effective? (Hint: Click the icon to view the frequency distributions Tar (mg) in Tar (mg) in D Nonfiltered Filtered Tar (mg) (Nonfiltered) (Filtered) Cigarettes Frequency Cigarettes Frequency 12- 15 2 4-7 4-7 % % 16 -19 2 8 -11 O W H 8-11 % 20 -23 13 12 -15 24-27 16 -19 15 12- 15 % 28 -31 16 - 19 % 20 -23 % 24-27 % 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, rces 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.
