The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. xx 11.3 8.4 7 3.7 2.5 2.2 2.1 0.6 yy 13.3 10.9 9.8 7.3 6.4 5.6 5.8 4.5 xx = thousands of automatic weapons yy = murders per 100,000 residents This data can be modeled by the equation y=0.82x+4.09.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 3.6 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 9.4 thousand automatic weapons?
The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
| xx | 11.3 | 8.4 | 7 | 3.7 | 2.5 | 2.2 | 2.1 | 0.6 |
|---|---|---|---|---|---|---|---|---|
| yy | 13.3 | 10.9 | 9.8 | 7.3 | 6.4 | 5.6 | 5.8 | 4.5 |
xx = thousands of automatic weapons
yy = murders per 100,000 residents
This data can be modeled by the equation y=0.82x+4.09.y=0.82x+4.09. Use this equation to answer the following;
