The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. x 11.6 8.3 6.6 3.3 2.9 2.8 2.6 0.3 y 13.6 11.1 9.7 6.6 6.8 6.6 6.4 4.3 x= thousands of automatic weapons y= murders per 100,000 residents This data can be modeled by the equation y=0.82x+4.2. Use this equation to answer the following; Special Note: I suggest you verify this equation by performing linear regression on your calculator. A) How many murders per 100,000 residents can be expected in a state with 2.2 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 7 thousand automatic weapons? Answer = Round to 3 decimal places.
