Chapter 1.3, Problem 13E

Licensed drivers. Table 8 contains the state population and the number of licensed drivers in the state (both in millions) for the states with population under 1 million in 2014. The regression model for this data is

$y=0.75x$

where $x$ is the state population (in millions) and $y$ is the number of licensed drivers (in millions) 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 Hawaii in 2014 was about 1.4 million, use the model to estimate the

number of licensed drivers in Hawaii in 2014 to the nearest thousand.

(C) If the number of licensed drivers in Maine in 2014 was about 1,019,000, use the model to

estimate the population of Maine in 2014 to the nearest thousand.
