a. very briefly interpret the estimated correlation coefficient...the direction and strength of the correlation
b. List and label the dependent variable and independent variable
c. based on regression results if a country's percentage of the population with at least a high school diploma increases by 1 by how much and in one direction does a country's median income change?
d. what is the predicted medinc for an HS degree of 70%
e. what proportion of the variation in medinc is explained by our regression model explained by variation in HS degree?
