Question

The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.

x

	11.5	8.2	6.6	3.3	2.3	2.8	2.7	0.7
y

	13.5	10.8	9.3	7	6.2	6.3	6.4	4.6

x = thousands of automatic weapons
y = murders per 100,000 residents

This data can be modeled by the equation y=0.81x+4.17. 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 8.4 thousand automatic weapons?

Answer = Round to 3 decimal places.

B) How many murders per 100,000 residents can be expected in a state with 8.7 thousand automatic weapons?

Answer = Round to 3 decimal places.

Answer 1

solution A) Here we find How many morders per 100,000 residents can be expected in a state with 8.4 thousand? from the given data The equation y=0.818+ 4 Here a= 8.4 y = 0.81 X(8.4)+ 4.17 = 6.804,74.17 - 10.974 Expected in a state with 8.4 thousand autoristic weapons is nie eet 10.974). B) He find expected in a state with 8.7 thousand automatic weapons Here a=8.7 Y = 0.81*68.7) +4.17 F t 7.041+ 4.17 y = [11.217). Bei
