You are interested in the psychological implications of high SES. You read a paper that claims that higher social class people behave more unethically. The paper reports a significant difference in the propensity of high and low SES people behaving unethically. The significance level of this study was 0.05, the ratio of true to false effects in this field is 0.35, but the author was anxious to issue a press release and prepare his TED talk, so power is low, at 0.1. The probability that this study reports a real effect is
A. 0.58
B. 0.95
C. 0.1
D. 0.35
E. 0.41
Solution
Ratio of true to false effects i.e T/F = 0.35
The power of the study indicates the real effect of the study and hence despite the true/false ration being 0.35 and the significance level of study is 0.05, the real effect of the study would be 0.1
Hence option C is correct

Jovi distributed 3(n+2) and got 3 x n + 3 x 6 is his answer correct
Answer:
Step-by-step explanation:
since 3 is outside the parenthesis (n + 2) you multiply the 3 by the n and the 2 and
3n + 6
next subtract the 6 and add the 6 to the other side
3n - 6 = 6
3n = 6
n = 2

In parallelogram ABCDwith diagonals AC and BD, which of the following is true?
Answer:
Last one at the bottom
Step-by-step explanation:
Because all of those diagonals are equal to each other. So that would mean those diagonals are equal in legnth.
BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Remember that the parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.
The diagonals of the parallelogram are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).
BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.

Find the distance between the pair of points.
(14, -1) and (-8, - 17)
Answer:
27.203 -or- √(740)
Step-by-step explanation:
Plug into square root formula to get
√((−8−14)²+(−17−(−1))²)
simplify
√(740)
Answer:
[tex]d=27.20[/tex] units or [tex]2\sqrt{185}[/tex] units
Step-by-step explanation:
(14, -1) and (-8, - 17)
To find the distance of two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Let's plug in what we know.
[tex]d = \sqrt{(-8-14))^2 + (-17-(-1))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-8-14))^2 + (-17+1)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-22)^2 + (-16)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(484) + (256) }[/tex]
Add.
[tex]d=\sqrt{740}[/tex]
Evaluate the square root.
[tex]d=27.20[/tex] units or [tex]2\sqrt{185}[/tex] units

A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative. Round answers to 4 decimal places where possible.
Answer:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative.
This means that [tex]n = 533, \pi = \frac{351}{533} = 0.6585[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 - 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6247[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 + 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6923[/tex]
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).

What is mid point theorem?The mid point theorem states that in a triangle the line segment joining the mid point of two sides is always parallel and equal to half of the length of the third side.
As per the given figure the data is as follows,
The line segment of length 6x + 7 is parallel to the side of a triangle of length 19x - 28 such that it divides other two sides equally.
Apply mid point theorem to obtain,
6x + 7 = 1/2(19x - 28)
=> 19x/2 - 6x = 14 - 7
=> 7x/2 = 7
=> x = 2
Hence, the value of x for the given triangle is 2.

Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1

3. (G.11C) A right cylinder has a total surface area of 1301 cm?. If the diameter of
the cylinder is 10 cm, what is the height?
X
A 8 cm
B 10 cm
C 9 cm
D 12 cm
Answer:
A. 8 cm
Step-by-step explanation:
Total surface of a cylinder = 130π cm²
Diameter (d) = 10 cm
Radius (r) = 10/2 = 5 cm
Height = ?
Formula for total surface area of cylinder = 2πrh + 2πr²
Plug in the values
130π = 2*π*5*h + 2*π*5²
130π = 10hπ + 50π
130π = π(10h + 50)
Divide both sides by π
130 = 10h + 50
Subtract 50 from each side
130 - 50 = 10h
80 = 10h
Divide both sides by 10
80/10 = 10h/10
8 = h
h = 8 cm

Answer:
AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm

Answer:
Binomial probability distribution concept & application, example
Step-by-step explanation:
Yes, this represents a binomial setting. As, it is used for finding probability of - particular number of success outcomes , from repetitive or multiple events.
Here
Success {Event P} ie small fish, with prob = 30% = 0.3 .Failure {Event Q} ie large fish, with prob = 70% = 0.7Number of trials = 20. Let r be number of small fishes out of 20 fishes.Binomial probability = N c r . (P)^r . (Q)^ (n-r)
