Question

2.14 Worldwide Child Mortality. Although child mortality rates worldwide have dropped by more than 50% since 1990, it is still the case that 16,000 children under five years old die each day. The mortality rates for children under five vary from 1.9 per 1000 in Luxembourg to 156.9 per 1000 in Angola. In Exercise 1.36 (page 41), you were asked to draw a histogram of this data. In this exercise, you will explore the relationship between child mortality and a measure of a country's economic wealth. One measure used by the World Bank is the gross national income (GNI) per capita, the dollar value of a country's final income in a year

Answer 1

Distribution for child mortality rates for countries in each of four economic classification is given as:

Based on gross national income

Low income-Child mortality rate is high

Lower middle income-Child mortality rate is less

upper middle income -Child mortality rate is less

High income -Child mortality rate is very less

Here Angola country seems to be outlier whose mortality rate is 156.9 but comes under the category of upper middle

here Aruba country mortality rate data is not given but it comes under the category of high economy

No economical classification given by world bank does not give the good explanation about the difference in child mortality rate across the countries

Firstly Child mortality rate of 22 countries are not available with world bank

So it can not be related with the economy of country due to non availability of data

Secondly Angola country whose mortality rate is 156.9 but it comes under the category of upper middle

Third Aruba country mortality rate data is not given but it comes under the category of high economy
