Answer:
Between 1991 and 2013, the infant mortality rate in the United States declined from 8.943% to 5.708 %
Step-by-step explanation:
From the information given:
The number of infant deaths under 1 year in the United States during 1991 = 36,766
The number of live births during 1991 = 4,111,000
[tex]Infant \ mortality \ rate \ in \ 1991 = \dfrac{Number \ of \ deaths \ under \ 1 \ year}{Total \ number \ of \ live \ births \ in \ 1991} * 1000[/tex]
[tex]Infant \ mortality \ rate \ in \ 1991 = \dfrac{36766}{4111000} * 1000[/tex]
Infant mortality rate in 1991 = 8.943%
From the data of year 2013 in the United States Record, 23,446 infants died under one year
[tex]Infant \ mortality \ rate \ in \ 1993= \dfrac{23,466}{4111000} * 1000[/tex]
Infant mortality rate in 1993 = 5.708 %
Between 1991 and 2013, the infant mortality rate in the United States declined from 8.943% to 5.708 % which is approximately 3%
Answer:
8.94 (mortality per 1,000 live births)
Step-by-step explanation:
Given;
Number of infant deaths in 1991 = 36,766
Number of live births during 1991 = 4,111,000
The infant mortality rate = Number of infant deaths ÷ Number of live births
The infant mortality rate (per 1,000 live births)
R = Number of infant deaths/Number of live births × 1000
Substituting the given values;
R = 36,766/4,111,000 × 1000
R = 0.00894 × 1000
R = 8.94 (mortality per 1,000 live births)
For 2013;
There's no data given for 2013.
It will follow the same procedure;
The infant mortality rate (per 1,000 live births) in 2013;
R2 = Number of infant deaths in 2013 Nd/Number of live births in 2013 Nb × 1000
R2 = Nd/Nb × 1000
