The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. x 11.8 8.3 6.8 3.3 2.8 2.5 2.6 0.7 y 13.8 11.3 9.6 6.6 6.5 6.5 6 4.3 x = thousands of automatic weapons y = murders per 100,000 residents This data can be modeled by the equation y = 0.85 x + 3.96 . 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 6.1 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 10.2 thousand automatic weapons? Answer = Round to 3 decimal places.
