Total Smokers-Dead+Alive=142+450=592.
Total Non Smokers-Dead+Alive=235+505=740.
a)Total Dead=142+235=377.
Total Alive=450+505=955
Proportion of smokers who died after 20 years=142/377.(1)
Proportion of non-smokers who died after 20 years=235/377.(2)
As Proportion(1) < Proportion(2) so it is healthier to smoke.
b)Proportion of smokers who are 18-24 and died=2/3.
Proportion of non-smokers who are 18-24 and died=1/3.
c)smokers dead in 25-34=4/10.
non smokers dead in25-34=6/10
35-44 smokers dead=14/22.
35-44 non smokers dead=8/22.
45-54 smokers dead=27/40
45-54 non smokers dead=13/40.
55-64 smokers dead=51/93
55-64 non smokers dead=42/93.
65-74 smokers dead=29/130
