Linear Regression Application, Interpolation and Extrapolation
Use the data and story to answer the following questions
The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.

x\displaystyle {x}11.786.73.92.42.62.60.3
y\displaystyle {y}14.211.19.77.46.46.16.44.3

x\displaystyle {x} = thousands of automatic weapons
y\displaystyle {y} = murders per 100,000 residents
Use your calculator to determine the equation of the regression line. (Round to 2 decimal places)

Determine the regression equation in y = ax + b form and write it below.

 
A) How many murders per 100,000 residents can be expected in a state with 7.1 thousand automatic weapons?

Answer = Round to 3 decimal places.
B) How many murders per 100,000 residents can be expected in a state with 1.7 thousand automatic weapons?

Answer = Round to 3 decimal places.
