Ans: B
Feedback:
Cause-specific mortality rates indicate the probability of death from a specific cause; the number of deaths from a specific disease is divided by the number of people in the population at midyear and multiplied by 100,000. Age-specific mortality rates indicate the probability of death among those of a specific age group; the number of deaths in the age group is divided by the number of people in that age group in the population at midyear and multiplied by 100,000. In calculating the case fatality rate, the number of people with a specific disease such as lung cancer becomes the subgroup being studied out of the entire population in a designated geographic area. Crude mortality rate is simply the number of deaths occurring in 1 year divided by the midyear population and multiplied by 100,000.
