Question

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 mortalityrate 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.
