Answer:
75%
Step-by-step explanation:
In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.
Quartile means a quarter of the data.
We're trying to find out what percentage of the students scored between 70 and 100.
70 is right on the 1st quartile mark, while 100 is on the maximum mark.
This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).
If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.
3/4 = 75%
Hence, the answer is 75%.
The chamber of commerce for a beach town asked a random sample of city-dwellers, "Would you like to live at the beach?” Based on this survey, the 95% confidence interval for the population proportion of city-dwellers who would like to live at the beach is (0.56, 0.62).
Based on this poll, a chamber of commerce member claims that more than half of city-dwellers would prefer to live at the beach.
Use the confidence interval to evaluate this claim and select the true statement.
Yes, it is reasonable to assume this because all reasonable values in the confidence interval are greater than 0.50.
We cannot determine this without taking a census of all city-dwellers.
No, it is not reasonable to assume this because another 95% confidence interval might not be entirely above 0.50.
No, it is not reasonable to assume this because there are only two choices and the proportion of city-dwellers who should prefer either is exactly 0.50, not more than 0.50.

What is the volume of a rectangular prism with the demensions: base 7 /2 cm, height 3 /2 cm, and length 9 /2 cm
Answer:
189/8 cm^3
Step-by-step explanation:
Given data
Base= 7/2 cm
Hieght= 3/2cm
Length= 9/2cm
We know that the expression for volume is
Volume = L*B*H
substitute our data
Volume= 7/2*3/2*9/2
Volume= 189/8 cm^3
Hence the volume is 189/8 cm^3

A helicopter is 2,500 feet above sea level. A pirate ship sunk with buried
treasure off the coast of Florida 125 years ago. It's depth is 3,000 feet
below the helicopter. How many feet below sea level is the pirate ship?
Answer:
500 feet below sea level
Step-by-step explanation:
You would take 2,500 and subtract 3,000 feet giving you an answer of -500 feet. Which means it is 500 feet below sea level

Answer:
r = 3 cm , LA= 30π cm^2 , SA = 48π cm^2
Step-by-step explanation:
This is a bit more difficult because we have to use the inverse formula
if
V = base area x height
we can obtain
base area = V/height
base area = 45π/5 = 9π cm^2
If
base area = radius^2 π
we can obtain
radius = √base area / π
r = √9 x π/π = 3 cm
base perimeter = 3 x 2 x π = 6π cm
LA = 6π x 5 = 30π cm^2
SA = 9π x 2 + 30 π = 48π cm^2

find the volume and surface area of each solid. you may use a calculator and use 3.14 as an approximation for pi
Answer:
Area = 452.16 cm²
Volume = 904.32 cm³
Step-by-step explanation:
The solid is a sphere, therefore,
Volume = ⁴/3πr³
Where,
π = 3.14
r = 6 cm
Volume = ⁴/3*3.14*6³
Volume = 904.319997 ≈ 904.32 cm³ (nearest hundredth)
Area = 4πr²
Area = 4*3.14*6²
Area = 452.16 cm²

Using the Substitution Method, find the value of y in the below system of equations?
-2y = 4x – 4
7x = -4y + 10
Answer:
y = 6
Step-by-step explanation:
-2y = 4x – 4
y = -2x + 2
7x = -4(-2x+2) + 10
7x = 8x-8+10
7x = 8x+2
7x -2 = 8x
-2 = x
plug this into the first equation and the value of y is 6
The value of y using substitution method on the given simultaneous equations is; y = -2
We are given the equations;
-2y = 4x - 4 - - -(eq 1)
7x = - 4y + 10 - - - (eq 2)
From eq 1, divide through by -2 to isolate y;
y = -2x + 2
Substitute -2x + 2 for y in eq 2 to get;
7x = -4( -2x + 2) +10
Expand the bracket to get;
7x = 8x - 8 + 10
7x = 8x + 2
8x - 7x = 2
x = 2
Put 2 for x in y = -2x + 2 to get;
y = - 2(2) + 2
y = -4 + 2
y = -2

Two sisters, sister A and sister B, play SCRABBLE with each other every evening. Sister A is a statistician, and she draws a random sample of 30 results from the 1,420 total games that have been played to construct a confidence interval estimate of p, the proportion of SCRABBLE games between her and her sister that she has won. Her 95% confidence interval estimate of p is LCL = 0.36, UCL = 0.69.
A 95% confidence interval estimate of the total number of games sister A has won out of the 1,450 games that have been played is LCL =___________ and UCL = ___________
The Illinois State Toll Highway Authority is conducting a study to estimate the proportion of low-income commuters who drive to work on a toll road. The project manager wants to estimate the proportion to within 0.03 with 95% confidence, and the project manager believes that p will turn out to be approximately 0.11.
A sample size no smaller than __________ is needed.
Answer:
First question: LCL = 522, UCL = 1000.5
Second question: A sample size no smaller than 418 is needed.
Step-by-step explanation:
First question:
Lower bound:
0.36 of 1450. So
0.36*1450 = 522
Upper bound:
0.69 of 1450. So
0.69*1450 = 1000.5
LCL = 522, UCL = 1000.5
Second question:
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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The project manager believes that p will turn out to be approximately 0.11.
This means that [tex]\pi = 0.11[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The project manager wants to estimate the proportion to within 0.03
This means that the sample size needed is given by n, and n is found when M = 0.03. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.11*0.89}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.11*0.89}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.11*0.89}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.11*0.89}}{0.03})^2[/tex]
[tex]n = 417.9[/tex]
Rounding up
A sample size no smaller than 418 is needed.
