Answer 1

$\begin{matrix} Tar(mg) &Relative~frequency~(Non filtered) &Relative~frequency~( filtered) \\ \hline 2-7& 0& 2/25*100=8\%\\ 8-13&0 &3/25*100=12\% \\ 14-19&2/25*100=8\% &5/25*100=20\% \\ 20-25& 2/25*100=8\% &15/25*100=60\% \\ 26-31& 13/25*100=52\% &0 \\ 32-37 &7/25*100= 28\% &0 \\ 38-43 &1 /25*100=4\% & 0 \end{matrix}\\ Yes, ~from~the~above~table~it~is~obvious~that~the~cigarette~filters~appear~to~be~effective.$
