Scenario: We’ll continue to examine the World Development Indicators data in the data table BirthRate 2005. We’ll broaden our analysis to work with other columns in that table:

 Region: country’s geographic region

 Fertil: number of births per woman  Mortmaternal: Maternal mortality, estimated deaths per 100,000 births  MortUnder5: deaths, children under 5 years per 1,000  MortInfant: deaths, infants per 1,000 live births

a. Perform a one-way ANOVA to decide whether birth rates are consistent across regions of the world. If you conclude that the rates differ, determine where the differences are.

b. Perform a one-way ANOVA to decide whether fertility rates are consistent across regions of the world. If you conclude that the rates differ, determine where the differences are.

c. Perform a two-way ANOVA to see how maternal mortality varies by length of maternity leaves and provider. If you conclude that the rates differ, determine where the differences are, testing for both main and interaction effects.

d. Perform a two-way ANOVA to see how mortality under five years of age varies by length of maternity leaves and provider. If you conclude that the rates differ, determine where the differences are, testing for both main and interaction effects.
