A follow-up study recorded 1,494 deaths in all, of which 911 occurred among men. What proportion of the deaths were among men?
A61.0%
B45.3%
C39.0%
D27.3%
Answer & Solution
Correct answer: A. 61.0%
1. A proportion needs the numerator inside the denominator, and the 911 male deaths are part of the 1,494 total deaths.
2. 911 divided by 1,494 equals 0.6098.
3. Multiplying by 100 gives 60.98%, which rounds to 61.0%.
4. 39.0% is the complement, the share of deaths among women.
5. 45.3% is the share of study participants who were men, which answers a different question.
6. 27.3% divides the 911 male deaths by the 3,340 men enrolled, giving the risk of death among men rather than the male share of deaths.
