Concept explainers
Licensed drivers. Table 9 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 2010. The regression model for this data is
where x is the state population and y is the number of licensed drivers in the state.
(A) Draw a
(B) If the population of Idaho in 2010 was about 1.6 million, use the model to estimate the number of licensed drivers in Idaho in 2010 to the nearest thousand.
(C) If the number of licensed drivers in Rhode Island in 2010 was about 0.75 million, use the model to estimate the population of Rhode Island in 2010 to the nearest thousand.
