Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
The Mexican government encouraged Americans to settle in Texas to prevent border violations form horse thieves and to protect the territory from Native American attacks. Also by encouraging American settlers to come to Texas, the farmers could purchase farm implements from the US to increase the flow of manufactured goods into Mexico.
Answer:Drug addicts will have an even greater need for quick cash to support their habits.
Explanation:
Interdiction refers to the fact that the government will forcefully stop the transportation of drugs .
When this happens this means no drugs are reaching the addicts and because they are already addicts and can no longer live without these drugs they will react hastily and commit crime.
They will get these reactions from their bodies that they can not control and as result they act irrationally and illogically.
