Consider a 95 percent confidence interval constructed for the difference between two population
proportions PR and Ps. The interval for PR - Ps is given as (-0.05, 0.15). Which of the following is an
appropriate interpretation of the confidence level?
In repeated random sampling with the same sample size, êr - Ộs will be contained in
the interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, PR will be contained in the
interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, Ôr will be contained in the
interval approximately 95 percent of the time.
The probability is 0.95 that the difference in the sample proportions PR - Ổs is between
-0.05 and 0.15
In repeated random sampling with the same sample size, approximately 95 percent of the
intervals will capture the difference in population proportions, PR - Ps.
Answer:
E
Step-by-step explanation:
In repeated random sampling with the same sample size, approximately 95 percent of the intervals will capture the difference in population proportions, PR - Ps.
Question is in the Picutre attached.
use the bar diagram to help you solve the equation 4x-12=16.
Answer:
x = 7
Step-by-step explanation:
4x−12=16
Step 1: Add 12 to both sides.
4x−12+12=16+12
4x=28
Step 2: Divide both sides by 4.
4x/4 = 28/4 = 7
x=7
I doing vertical angles and I'm way too confused to even understand
Erotically angles are opposite each other and equal the same degree.
In the image 5x and 120 are vertical angles so 5x needs to equal 120.
X = 120/5
X = 24
Answer:
X=24 degrees.
Step-by-step explanation:
120/5=24. You divide by 5, because the angles will be congruent, and the top angle is 5*_=120. And 5*24=120, so x=24

Answer:
5
Step-by-step explanation:
5+12= 17
Equation/Question:
P+12=17 What does P equal in this situation?
Answer/Steps to answer:
1. Subtract 12 from both sides.
p=17-12
2. Simplify 17-12 to 5.
p=5
-------------------
Checking:
P+12=17
1. Let p=5.
5+12=17
2. Simplify 5+12 to 17.
17=17

Enter
Answer: 6.25
Step-by-step explanation:
a2 + b2 = c2
b2 = c2 - a2
b2 = (8*8) - (5*5)
b2 = 64 - 25
b2 = 39
b = [tex]\sqrt{39}[/tex]
b = 6.25

The weight in gram of 15 packets of sweets are: 55.0,55.3,55.3,55.3,55.5,55.6,55.8,55.9,56.1,56.2,56.2,56.4,56.7,56.7,56.8. Write down the value of the medium and quartiles
Given:
The weight in gram of 15 packets of sweets are: 55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8.
To find:
The value of the median and quartiles.
Solution:
We have,
55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8
Divide the data set in two equal parts.
(55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8)
Divide each parenthesis in two equal parts.
(55.0, 55.3, 55.3), 55.3, (55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2), 56.4, (56.7, 56.7, 56.8)
Now,
First quartile = 55.3
Second quartile = Median = 55.9
Third quartile = 56.4
Therefore, the median is 55.9 and the three quartiles are 55.3, 55.9, 56.4 respectively.
find the x (please help lol)
Answer:
x = 23.5
Step-by-step explanation:
x is the midsegment theorem of the trapezoid given.
Based on the midsegment theorem of a trapezoid, thus:
x = (7 + 40)/2
x = 47/2
x = 23.5
9.Patients who are addicted to cocaine are sometimes using the drug to combat
depression. As such, sometimes addicts are given antidepressant medications to
prevent relapse. A three-year study compared the effects of two such medications,
lithium and desipramine, along with a placebo for 72 cocaine users wishing to break
the habit. The patients were put into 3 groups of 24, and given 1 of the 3 treatments at
random. This two-way table illustrates the results.
Treatment Relapse No relapse Total
Desipramine 10 14 24
Lithium 18 6 24
Placebo 20 4 24
Total 48 24 72
According to the table, 48 of the addicts relapsed regardless of the treatment given.
This number is an example of a
A. relative frequency
B. marginal frequency.
C. conditional relative frequency.
D. joint frequency

Write an equation for the function whose graph is described.
The shape of f(x) = |x|, but shifted 19 units up and then reflected in the x-axis
Answer:
f(x)=-|x|+19
Step-by-step explanation:
so shifted 19 units up means
abosolute value of x + 19
and reflected in the x axis means that you have to put the - before the abosolute value.
so -|x|+19

Quotient of 59.4 and 8.25 show work
Answer:
in previous material it was shown that the digit sum of the product of two integers is equal to the digit sum of the product of the digit ... For instance, 66/8 = 8.25. ... For example, 35/7=5; the digit sum of the quotient is 5 and the digit sum of 35 is 8.
Missing: 59.4 | Must include: 59.4
Answer:
7.2
Step-by-step explanation:
Change the divisor 8.25 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
5940 ÷ 825 = 7.200
and therefore:
59.4 ÷ 8.25 = 7.200
Both calculated to 3 decimal places.

Find the x and y intercepts Y-2xy+4x=1
Answer:
[tex]x = \frac{1}{4}[/tex]
[tex]y= 1[/tex]
Step-by-step explanation:
Given
[tex]y - 2xy + 4x = 1[/tex]
Solving (a) The x intercept
Let y = 0
[tex]y - 2xy + 4x = 1[/tex]
[tex]0 - 2x*0 + 4x = 1[/tex]
[tex]0 - 0 + 4 x = 1[/tex]
[tex]4x = 1[/tex]
Divide both sides by 4
[tex]x = \frac{1}{4}[/tex]
Let x = 0
[tex]y - 2xy + 4x = 1[/tex]
[tex]y - 2y * 0 + 4*0 = 1[/tex]
[tex]y - 0 + 0 = 1\\[/tex]
[tex]y= 1[/tex]
