The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
| xx | 11.7 | 8.6 | 7.1 | 3.5 | 2.5 | 2.4 | 2.1 | 0.7 |
|---|---|---|---|---|---|---|---|---|
| yy | 14.2 | 11.5 | 10 | 6.8 | 6 | 6.4 | 5.8 | 4.4 |
xx = thousands of automatic weapons
yy = murders per 100,000 residents
This data can be modeled by the equation y=0.88x+3.91.y=0.88x+3.91. 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 10.2 thousand automatic weapons?
