Perinatal mortality rate per 1000 total births is 35. If there were 700 late fetal deaths and early neonatal deaths combined, the number of total births (live births + stillbirths) is: MCQ with Answer and Explanation
Perinatal mortality rate per 1000 total births is 35. If there were 700 late fetal deaths and early neonatal deaths combined, the number of total births (live births + stillbirths) is:
A. 2,000
B. 35,000
C. 24,500
D. 20,000
Answer: Option D
Solution (By JKSSB Mock Tests)
Rate = (perinatal deaths / total births) × 1000 => 35 = 700 / total births × 1000 => total births = 700,000/35 = 20,000.
Explanation:
Expected (AB) = (A)×(B)/N = 400×500/1000 = 200,000/1000 = 200. Observed 250 > 200 suggests positive association between attributes A and B.
