Construct one table that includes relative frequencies based on the frequency distributions shown below, then compare K 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 relative frequency table below. Relative Relative Frequency Frequency Tar (mg) (Nonfiltered) (Filtered) 3-6 % % 7-10 % % 11 -14 % % 15 - 18 % % 19 -22 % % 23-26 % % 27 -30 % % (Simplify your answers.)
