Question Completion:
(a) Identify the experimental unit.
(b) Define the population of interest to the Census Bureau.
(c) Identify the sample.
(d) What variable is being measured? Is it quantitative or qualitative?
(e) Describe the statistical inference that the economists intend to make.
Answer:
a. The experimental unit is the households visited.
b. The population of interest to the Census Bureau is all US-based individuals aged 14 and above.
c. The sample is 59,000 households.
d. The variable under measure is quantitative (percentage estimate of people in the labor force who are unemployed).
e. The economists want to make a statistical inference of the unemployed population based on the sample data analysis that they conduct.
Step-by-step explanation:
a) Data and Calculation:
Population of interest = 98 million households
Sample from population = 59,000 households
b) The unemployment rate is the percentage of the total workforce of a country that is unemployed and who may be actively seeking employment at a particular period. This implies that the unemployment rate may include persons who are active members of the workforce but may be underemployed.

try substituting the points into both of the equations like it's a slope equation.
Write the equation in slope-intercept form.

5y = 35
Answer:
y = -x + 7
General Formulas and Concepts:

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityAlgebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
[Standard Form] 5x + 5y = 35
Step 2: Rewrite
Find slope-intercept form.
Subtract 5x on both sides: 5y = -5x + 35Divide 5 on both sides: y = -x + 7An art teacher mixes 5 parts blue paint and 3 parts white paint to make a light blue color to paint a Tar Heels logo on a school mural. If she needs a total of 40 gallons of light blue paint to paint the mural, how many gallons of blue paint will she use?
Answer:
50
Step-by-step explanation:
For starters, we make the following assumptions
Let the blue paint be represented by x
Let the white paint be represented by y
Now, forming an inequality equation from the question, we can say that
5x + 3y = 1
And from the second part, we are told that 40 gallons of light blue paints are needed.
If 5x + 3y = 1, then multiplying all by 40, we have
200x + 120y = 40
This means that 200 parts of blue paints is needed to be mixed with 120 parts of white paints to get the desired 40 gallons.
There are 4 parts in a gallon, so 200 parts = 200/4 gallons, = 50 gallons of blue paints

64 3/4 is equivalent to
The Equivalent fraction to 64 3/4 is 259/4.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.We have 64 3/4.
First change the mixed fraction into normal fraction as
64 3/4
= (4 x 64+3)/ 4
= 259/4

Answer:
4 hours.
Step-by-step explanation:
Okay, so they leave the same port. Since they are traveling at the same rate at 24mph, in one hour they will each be 24 miles from the port. Since they are going in opposite directions, they will be 24+24= 48 miles apart. Let another hour pass. They each go 24 more miles from the port so add another 48 to their distance apart. Now their distance is 96 miles apart. Let a third hour pass. Add 48. Now their distance is 144 miles apart. Let the fourth and final hour pass. Now they are 192 miles apart. So, it'll take them 4 hours to be 192 miles apart.
A visual way to interpret this problem is on a number line. We'll have steamer A going to the right of our origin 0 (the port) and steamer B going left. After one hour, steamer A will be at 24 on the number line, and steamer B will be at -24. the distance between these two points is 48. If you continue with the second, third and fourth hours they will each be going 24 points further from the origin, making their distance grow further and further apart by 48 points each hour.

16. Which statement best describes a margin of error?
A. the difference between a sample mean and a population proportion
B. the value of error between a sample mean and a population proportion
C. the difference between a sample mean and a population mean
D. the value of error between a sample statistic and an actual population parameter
Answer: D. the value of error between a sample statistic and an actual population parameter
Step-by-step explanation:
In a study , the margin of error gives the amount of the random variation of the actual result from its estimation.
So, it is the value of error between a sample statistic( which is estimated population parameter until actual is known) and an actual population parameter.
Hence, the best statement to represent the margin of error :
D. the value of error between a sample statistic and an actual population parameter

The graph is shown in figure attached.
Step-by-step explanation:
We need to solve the inequality and graph the solution.
[tex]m - 6 > 2[/tex]
First solve the inequality
[tex]m - 6 > 2\\[/tex]
Adding 6 on both sides
[tex]m-6+6>2+6\\m>8[/tex]
Solving the inequality [tex]m - 6 > 2[/tex] we get [tex]\mathbf{m> 8}[/tex]

Required
Calculate the constant of proportionality.
Represent the required constant with k.
Such that:
[tex]k = \dfrac{y}{x}[/tex]
Pick any two corresponding values of x and y
[tex](x,y) = (1,40)[/tex]
This means that:
[tex]x = 1\ and\ y = 40[/tex]
[tex]k = \dfrac{y}{x}[/tex] becomes

Wich equation has a solution of 2/3 for n?
Answer:
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Step-by-step explanation:
We need to find out of 4 options which equation has a solution of 2/3 for n.
Equation (1).
[tex]n-1=\dfrac{1}{3}\\\\n=\dfrac{1}{3}+1\\\\n=\dfrac{4}{3}[/tex]
Equation (2).
[tex]16n=24\\\\n=\dfrac{24}{16}\\\\n=\dfrac{3}{2}[/tex]
Equation (3).
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Equation (4).
[tex]1\dfrac{1}{3}+n=3\\\\n=3-\dfrac{4}{3}\\\\n=\dfrac{5}{3}[/tex]
So, equation (3) has a value of n as 2/3. Hence, the correct option is (3).
