Based on these SMRs alone, it is possible to conclude that: a. 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 b. 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 c. The age-adjusted rate of death from lung cancer in bricklayers was greater in 1949 - 1960 than it was in 1968-1979 d. 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 e. 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

d. 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

Explanation:

SMRs - Standardized mortality ratios are useful for measuring whether a population, made-up of workers in a certain industry, has higher mortality than what would be expected if the population had the same mortality rate as those in the general population.

SMRs = (observed number of deaths) / (expected number of deaths.)

This tool is used as an indirect method to adjust age expectation.

To draw inferences, when the ratio of SMRs is greater than 1 (or 100 when multiplied by this amount to remove the decimal).

This shows that the occupational demographic grouping has a higher mortality rate than what would be expected for a similar group of people of differing ages who are representative of a series of occupations, not just carpentry.
