Scenario: We will continue to examine the World Development Indicators data in BirthRate 2017. We will broaden our analysis to work with other variables:

╶ Provider: Source of maternity leave benefits (public, private, or a combination of both)

╶ Fertil: Average number of births per woman during child-bearing years

╶ MortUnder5: Deaths of children under 5 years per 1,000 live births

╶ MortInfant: Deaths of infants per 1,000 live births

a. Create a mosaic plot and contingency table for the Provider and Region columns. Report on what you find.

b. Use appropriate methods to investigate how fertility rates vary across regions of the world. Report on what you find.

c. Create a scatterplot for MortUnder5 and MortInfant. Report the equation of the fitted line and the R-square value, and explain what you have found.

d. Is there any noteworthy pattern in the covariation of Provider and MatLeave90+? Explain what techniques you used, and what you found.
