Question:
The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
xx | 11.3 | 8.4 | 6.6 | 3.5 | 2.4 | 2.4 | 2.4 | 0.3 |
---|---|---|---|---|---|---|---|---|
yy | 13.5 | 11.5 | 9.7 | 6.7 | 6.2 | 6 | 5.8 | 4.1 |
xx = thousands of automatic weapons yy = murders per 100,000 residents This data can be modeled by the equation y=0.87x+3.87.y=0.87x+3.87. 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 4.6 thousand automatic weapons? Answer = Round to 3 decimal places.
