If a​ rifleman's gunsight is adjusted correctly but he has shaky​ arms, he might shoot bullets scattered widely around the​ bull

's-eye target. Draw a sketch of the target with the bullet holes. Does this show variation​ (lack of​ precision) or​ bias? b. Draw a second sketch of the target if the shots are both unbiased and precise​ (have little​ variation). The​ rifleman's aim is not​ perfect, so your sketches should show more than one bullet hole.

Answer:

Explanation:

Not going to draw but I will answer it theoretically.

The shots that are consistently 2 feet left means his aim is fine but his sites are off.  It shows no lack of precision.

The second one is pretty simple aswell. every rifleman can't shoot the same hole every single shot. Many things affect it but the same technique the same time for every shot with "zero'd" sights means the rounds should be inpacting within a relativly small shot group.

What was the ultimate colonial objection to the Sugar Act?
Harman [31]
The ultimate colonial objection to the Sugar Act was that it was taxation without representation. The colonists were being taxed from Great Britain without someone representing their rights and ideas in Parliament in London. They were also unfairly being taxed to bring more money into the colonial superpower, instead of it being used for the Thirteen Colonies.

3.6.46-T Consider the following sample data for two variables. x 7 8 5 3 9 y 7 5 9 7 7 a. Calculate the sample covariance. b. Ca
Mrac [35]

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

r=\frac{sum(x-xbar)(y-ybar)}{\sqrt{sum(x-xbar)^2sum(y-ybar)^2} }

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=\frac{-6}{\sqrt{23.2(8)} }

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.
