Infant mortality rate is defined as the number of babies that
die between birth and age 1 per 1000 live births. For example, an
infant mortality rate of 23.4 means that for every 1000 babies born
23.4 will die before age 1. We are using rates in this project
because it allows us to compare regions with different population
sizes.

1. Provide descriptive statistics (Mean, median, variance,
standard deviation, and the five number summary) for infant
mortality rate for each region.
2. Provide descriptive statistics (Mean, median, variance,
standard deviation, and the five number summary) for under five
mortality rate for each region.
3. Construct a side-by-side box plot for infant mortality rate
and region. Please compare similarities or dissimilarities among
the regions.
4. Construct a 95% confidence interval for the average infant
mortality rate. Be sure to write a statement summarizing your
findings
5. Construct a 95% confidence interval for the average
under-five mortality rate. Be sure to write a statement summarizing
your findings.
6. Test if the African average infant mortality rate is
different from 62.56 using the population standard deviation 27.91
and normal distribution for α=0.05.
7. Describe what you have learned about the global infant
mortality rate and under five mortality rate.
8. Provide your recommendation that would improve infant
mortality rate and under five mortality rate based on evidence
obtained from credible literature reviews.
