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. Complete the following relative frequency table. (Round to the nearest percent as needed.) Relative Frequency Relative Frequency Tar (mg) (Nonfiltered) (Filtered) 2-7 % % 8-13 % % 14-19 % % 20-25 % % 26-31 % % 32-37 % % 38-43 % % Frequency Distributions Tar (mg) in Nonfiltered Cigarettes Frequency 14-19 20-25 26-31 32-37 38-43 2163 Tar (mg) in Filtered Cigarettes Frequency 2-7 3 8-13 14-19 5 20-25 16
