The expected number of deaths in this occupational group, based on age-specific death rates for lung diseases in all males ages 20 to 64 years, was 238 during 1990. What was the standardized mortality ratio (SMR) for lung diseases in miners? • O A. 100% • O B 250% • O C. 80.6% • O D. 192% Reset Selection

Answer 1

Standardized mortality ratio = Number of deaths $\div$ expected deaths $\times$ 100

                                             = 192 $\div$ 238 $\times$ 100

                                             = 80.6%

Option C is the correct answer.
