In a meat processing plant with 1,200 employees in an impoverished county, records showed that there were 20 deaths over a one-year period. Analyses showed that in a similarly aged population (of the same size) in a nearby town, one would have only expected to see 16 deaths. How would one describe mortality at this plant in such a way as to account for the workers' ages?

Select one:

a. As a mortality rate of 1.7%

b. As a mortality rate of 1667 per 100,000

c. SMR=125

d. SMR=66.7

e. You would need to know the person years at the plant.
