Question

Calculate the infant mortality rate (per 1,000 live births) from the following data:________.

Answer 1

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

$Infant \ mortality \ rate \ in \ 1991 = \dfrac{Number \ of \ deaths \ under \ 1 \ year}{Total \ number \ of \ live \ births \ in \ 1991} * 1000$

$Infant \ mortality \ rate \ in \ 1991 = \dfrac{36766}{4111000} * 1000$

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

$Infant \ mortality \ rate \ in \ 1993= \dfrac{23,466}{4111000} * 1000$

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 2

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
