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}11.68.57.23.52.42.52.50.4
y\displaystyle {y}13.711.510.26.76.46.15.94.2

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 1.9 thousand automatic weapons?

Answer = Round to 3 decimal places.
B) How many murders per 100,000 residents can be expected in a state with 10.5 thousand automatic weapons?

Answer = Round to 3 decimal places.
