Question 1176089
the formula to use is:


y = .87 * x + 4.06


when x = 7, y = .87 * 7 + 4.06 = 10.15


when x = 9, y = .87 * 9 + 4.06 = 12.064.


this translates to:


when the number of automatic weapons is equal to 7,000, then the number of murders per 100,000 is equal to 10.15.


when the number of automatic weapons is equal to 9,000, then the number of murders per 100,000 is equal to 12.0564.


the correlation is positive.


the higher the number of automatic weapons, in thousands, the greater the murder rate per 100,000 residents.
