The total fertility rate (TFR) is the sum of age-specific fertility rates multiplied by the width of age interval. If 5-year groups, it is multiplied by: MCQ with Answer and Explanation
The total fertility rate (TFR) is the sum of age-specific fertility rates multiplied by the width of age interval. If 5-year groups, it is multiplied by:
A. 1
B. 5
C. 10
D. 1000
Answer: Option B
Solution (By JKSSB Mock Tests)
TFR = 5 × Σ ASFR (per woman) if ASFR are computed per 1000 women per 5-year interval and divided by 1000 appropriately. Actually, if ASFRs are in per 1000, TFR = 5 × Σ ASFR_i / 1000.
Consider the following statements about probability: 1. For any two events, P(A∪B) ≤ P(A) + P(B). 2. If A ⊆ B, then P(A) ≤ P(B). 3. For independent events, P(A|B) = P(A). Which of the above is/are correct?
