Answer 1

The total frequency for non-filtered cigarettes = 1 + 14 + 7 + 3 = 25
Relative frequency % for each cell = Cell frequency * 100 / 25 = Cell frequency * 4

The total frequency for filtered cigarettes = 2 + 2 + 7 + 14 = 25
Relative frequency % for each cell = Cell frequency * 100 / 25 = Cell frequency * 4

Relative frequency distribution is,

Tar (mg)	Relative frequency (Non-filtered)	Relative frequency (Filtered)
7-11	0	8
12-16	0	8
17-21	4	28
22-26	0	56
27-31	56	0
32-36	28	0
37-41	12	0
