from Silva and Tenreyro (2017), plots the total fertility rate against real per capita income for 88 countries in 1960 (circles) and in 2013 (triangles). Figure 3 Fertility-Income Relation in 1960 and 2013 O 1960 4 2013 Fited line 1960 Fitted line 2013 GDP per capita (USS) Source: Authors using data from the World Development Indicatorn database. Note For a sample of 88 countries, the figure shows the scanerplos and fined line (that is, the kowess smoothed relationship or locally weighted snoothing function) between the total fertility rate and log of per capita GDP (in constant 2005 USS) in 1960 and 2013. The xaxis is log scale. Describe in words what the figure reveals about the relationship be- tween the level of income per capita and fertility in 2013 across countries and discuss to which extend the empirical relationship observed in 2013 is or is not consistent with the predictions of the Solow growth model with population growth, which takes fertility as exogenously given.

Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
