Explanation / Answer

Relative frequency = the frequency of a group / the summition of total frequencies

Here total frequencies for non filtered cigarettes = 25

total frequencies for filtered cigaretted = 25

Hence the relative frequencies are :

Tar(mg)       Relative frequency non filtered            Relative frequency filtered

7-12                          -                                                 0.08

13-18                        -                                                 0.12

19-24                       0.04                                             0.24

25-30                       0.08                                             0.56

31-36                       0.56                                               -

37-42                       0.28                                               -
