Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.
Answer:
Sample third quartile appears to be an unbiased estimator of the population third quartile.

Which expression represents the ratio of the difference of the two means to Sidney's mean absolute deviation
Answer:
The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195
Step-by-step explanation:
P.S - The exact question is -
Given - The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below.
Sidney’s Grades Phil’s Grades
Mean 82 78
Mean Absolute Deviation 3.28 3.96
To find - Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?
Proof -
Given that Mean of Sidney Grades = 82
Mean of Phil's Grades = 78
So,
The difference of two means = 82 - 78 = 4
Also,
Given, Mean Absolute Deviation of Sydney = 3.28
Now,
The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195

Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=
Answer:
x = 4.3
Step-by-step explanation:
Given the question :
Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=
Taking out the equation :
1.2x = 5.16
Divudse both sides by 1.2
1.2x/1.2 = 5.16 / 1.2
x = 4.3
Hence, x = 4.3
The value of x in the equation is equal to 4.3
Data;
1.2x = 5.16Linear EquationTo solve this problem, we need to first make x the subject of formula and this is done by dividing both sides of coefficient of x.
[tex]\frac{1.2x}{1.2} = \frac{5.16}{1.2}[/tex]
This can be further simplified as
[tex]x = \frac{5.16}{1.2} = 4.3[/tex]
The value of x in the equation is equal to 4.3

Solve the problem by entering and solving an equation.
A rectangular picture frame has a perimeter of 58 inches. The height of the frame is 12 inches. What is the width of the frame
Answer:
15 inches
Step-by-step explanation:
Substitute the formula
Let 'x' be the other side
2 [ l + b ] = Perimeter
2 [ 12 + x ] = 58
12 + x = 58 divided by 2
x = 27 - 12
= 15
Therefore 15 inches is the other side.

Of Linear Eqitions by
Elimination
3x-y=0
2x+y=-10
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)

Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9

In the diagram, the measure of angle 3 is 76°.
A transversal intersects 2 lines to form 8 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8.
What is the measure of angle 4?
Answer:
Alright, lets get started.
Angle 3 and angle 4 are adjacent angles because they are having the common side.
They both are on straight line, so, their addition will be 180°.
Suppose angle 4 is x , hence
angle 4 + angle 3 = 180
Subtracting 89 from both sides

Find the quotient
6 1/2 divided by 3/4
Answer:
8 2/3
Step-by-step explanation:
First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2 divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.
