Licensed drivers. The table contains the state population and the number of licensed drivers in the state (both in millions) for the states with population over 10 million in 2010. The regression model for this data is
y = 0.63x + 0.31
where x is the state population and y is the number of licensed drivers in the state.

(A) Draw a scatter plot of the data and a graph of the model on the same axes.
(B) If the population of Minnesota in 2010 was about 5.3 million, use the model to estimate the number of licensed drivers in Minnesota in 2010 to the nearest thousand.
(C) If the number of licensed drivers in Wisconsin in 2010 was about 4.1 million, use the model to estimate the population of Wisconsin in 2010 to the nearest thousand.
