Question

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

x |
---|

11.3 | 8.4 | 7.1 | 3.6 | 2.5 | 2.7 | 2.4 | 0.4 | |

y |

13.4 | 10.9 | 9.9 | 7.1 | 5.9 | 6 | 6 | 4.2 |

x = thousands of automatic weapons

y = murders per 100,000 residents

This data can be modeled by the equation y=0.84x+3.88. Use this
equation to answer the following;

A) How many murders per 100,000 residents can be expected in a
state with 3.9 thousand automatic weapons?

Answer = Round to 3 decimal places.

B) How many murders per 100,000 residents can be expected in a
state with 1.1 thousand automatic weapons?

Answer = Round to 3 decimal places.

Answer #1

The equation is y=0.84x+3.88

where x = thousands of automatic weapons,

y = murders per 100,000 residents

A) The number of murders per 100,000 residents can be expected in a state with 3.9 thousand automatic weapons is nothing but the value of y when x=3.9.

Therefore, the value of y = 0.84*(3.9) + 3.88

y = 7.156

Therefore, **the number of murders per 100,000 residents
can be expected in a state with 3.9 thousand automatic weapons is
7.156.**

**B)**

The number of murders per 100,000 residents can be expected in a state with 1.1 thousand automatic weapons is nothing but the value of y when x=1.1.

Therefore, the value of y = 0.84*(1.1) + 3.88

y = 4.804

Therefore, **the number of murders per 100,000 residents
can be expected in a state with 1.1 thousand automatic weapons is
4.804.**

A regression was run to determine if there is a relationship
between hours of TV watched per day (x) and number of situps a
person can do (y).
The results of the regression were:
y=ax+b
a=-1.082
b=36.749
r2=0.6889
r=-0.83
Use this to predict the number of situps a person who watches 7
hours of TV can do (to one decimal place)
