The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. 11.9 8.5 3.5 2.3 2.7 2.6 0.3 13.8 11.1 10 5.7 6.4 6.4 4.3 I = thousands of automatic weapons y = murders per 100,000 residents This data can be modeled by the equation y = 0.82x + 4.09. 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 6 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 10.6 thousand automatic weapons? Answer = Round to 3 decimal places.
