Pack-and-Move conducted a study that showed 98% customer satisfaction,

with a standard deviation of 1%. The sample included 25 people who

appeared in one of their commercials, during the past 5 years.

Move-Em-Out conducted a study that showed 92% customer satisfaction,

with a standard deviation of 3%. The random sample consisted of 100 people,

who had recently hired the moving company.

Which of the company claims is more believable and why?

O

A. Pack-and-Move because the time span was longer.

O

B. Pack-and-Move because the standard deviation is smaller.

O

C. Move-Em-Out because the sample was not biased.

O

D. Move-Em-Out because the standard deviation is larger.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
