Data from the World Bank for 25 Western Hemisphere countries was used to examine the association between (average) female life expectancy (that is, the average lifespan of women in the country) and the average number of children women give birth to. Given below is the scatterplot for the data. The regression equation for this context is found to be y with logical and on top = 84.5 - 4.4x where y is female life expectancy in years, and x is the average number of births per woman. Interpret the slope in the context of the study. Expect to see an increase of 84.5 years in female life expectancy when the average number of births per woman in a country increases by one child. When a country has zero births per woman on average, predict a female life expectancy of 4.4 years. When a country has zero births per woman on average, predict a female life expectancy of 84.5 years. Expect to see a decrease of 4.4 years in female life expectancy when the average number of births per woman in a country increases by one child. Question 4
