Question
The following are standardized morality ratios (SMRs) for lung cancer in England:
STANDARDIZED MORTALITY RATIO
Occupation
1949-1960
1968-1979
Carpenters
Bricklayers
209
142
135
118
Based on these SMRs alone, it is possible to conclude that:
The number of deaths from lung cancer in carpenters in 1949-1960 was greater than the number of deaths from lung cancer in bricklayers during the same period
The proportionate mortality from lung cancer in bricklayers in 1949-1960 was greater than the proportionate mortality from lung cancer in the same occupational group in 1968-1979
The age-adjusted rate of death from lung cancer in bricklayers was greater in 1949-1960 than it was in 1968-1979
The rate of death from lung cancer in carpenters in 1968-1979 was greater than would have been expected for a group of men of similar ages in all occupations
The proportionate mortality rate from lung cancer in carpenters in 1968-1979 was 1.35 times greater than would have been expected for a group of men of similar ages in all occupations.
