Researchers aim to determine what is the true average proportion of people in the U. S. pay their credit card bills on time. Researchers sample 50 U. S. homes at a time, and calculate within each sample the average proportion of people that pay their credit card bills on time. The data from these samples of 50 U. S. people is shown on the sampling distribution below. Identify what one of the dots above the number "0.32" means. Select the best answer from the options below.

In the sample of 50 U. S. people, one person paid their credit card bills on time 32% of the time.

2 people in a sample of 50 U. S. people paid their credit card bills on time 32% of the time.

In one sample of 50 U. S. people, the average proportion of people who pay their credit card bills on time is 32%

step-by-step explanation:

thats the first half

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
