Question

C.C.TO 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 relative frequency table below. i Frequency Distributions Relative Frequency Relative Frequency Filtered) Tar (mg) (Nonfiltered) 2-6 7-11 12-16 17-21 22-26 27-31 32-36 Tar (mg) in Nonfiltered Tar (mg) in Filtered 12-16 17-21 22-26 27-31 32-36 2-6 7-11 12-16 17-21 13 13 (Simplify your answers.)

Explanation / Answer

Relative frequacy= Frequency/ Number of frequency *100

Tar Frequency Rel Freq % Nonfiltered Filtered Nonfilterd Filtered 2-6 0 3 0 12 7-11 0 2 0 8 12-16 1 7 4 28 17-21 2 13 8 52 22-26 13 0 52 0 27-31 7 0 28 0 32-36 2 0 8 0 Sum 25 25
