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. 11.3 8 7.1 3.8 2.7 2.3 2.2 0.6 y | 13.9| 10.8| 10.2| 7.4 6 6.3 6.1 4.6 x = thousands of automatic weapons 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 = bo + by(x) form and write it below.
