Answers
Option B. Because when you have quantitative data, but assumptions of normality are not met. This is because, unlike parametric tests, non-parametric tests do not make assumptions about the data's underlying distribution.
Why should we use non-parametric tests? Option B. Because when you have quantitative data, but assumptions of normality are not met.Non-parametric tests are often used when dealing with data that is not normally distributed, as they allow for a more accurate analysis of such data. They can also be used when a linearity of the data cannot be assumed and when dealing with ordinal data. Non-parametric tests are more powerful than parametric tests, which makes them a good choice when a more precise analysis is needed.

4. this problem is also from ars magna. find two numbers such that the sum of their squares is 100. the square of the larger number is equal to the sum of the product of the larger number and four times the smaller number and eight times the larger number. let x and y be the two numbers such that x
Answers
The two numbers that satisfy both conditions are from quadratic equation :x =
1) -10/3, y = ±(10√7)/3
2)x = 10/3, y = ±(10√7)/3.
Let's denote the two numbers as x and y. We are given the following information:
1. The sum of their squares is 100: x^2 + y^2 = 100.
2. The square of the larger number is equal to the sum of the product of the larger number and four times the smaller number and eight times the larger number: y^2 = x(4y + 8x).
To solve this problem, we can start by simplifying the second equation. By expanding the equation, we get:
y^2 = 4xy + 8x^2.
Now, we can substitute this equation into the first equation to eliminatey:
x^2 + (4xy + 8x^2) = 100.
Combining like terms, we have:
9x^2 + 4xy - 100 = 0.
To find the values of x and y that satisfy this equation, we can use various methods such as factoring, completing the square, or the quadratic formula. In this case, let's solve it by factoring.
Factoring the quadratic equation, we get:
(3x + 10)(3x - 10) = 0.
Setting each factor equal to zero, we have two possibilities:
1. 3x + 10 = 0, which gives x = -10/3.
2. 3x - 10 = 0, which gives x = 10/3.
Now that we have the values of x, we can substitute them back into one of the original equations to find the corresponding values of y. Let's use the first equation:
For x = -10/3, we have (-10/3)^2 + y^2 = 100. Solving this equation, we find y = ±(10√7)/3.
For x = 10/3, we have (10/3)^2 + y^2 = 100. Solving this equation, we find y = ±(10√7)/3.
Therefore, the two numbers that satisfy both conditions are:
1. x = -10/3, y = ±(10√7)/3.
2. x = 10/3, y = ±(10√7)/3.
These are the two sets of numbers that meet the given conditions.

In a classroom of 20 students, 70% of them have brown eyes. If a teacher picks two students

eyes?

A)
100

C)
38
9
D)
100
Answers
Answer:
The probability is 9/100
Step-by-step explanation:
First, we know that 70% of the students are with brown eyes. Since we have a total of 20 students, this corresponds to 70/100 * 20 = 14 students
The number of students without brown eyes is thus 20 -14 = 6 students
Now, the probability of selecting a student without brown eyes is 14/20 = 7/10 while the probability of selecting a student with brown eyes is 6/20 = 3/10
Now the probability of selecting two students without brown eyes mean, the first selected is without brown eyes and also the second selected is without brown eyes.
In probability, once we have the work and, we multiply.
So our answer here is 3/10 * 3/10 = 9/100

n a certain college class, 55% of the admitted students were in the top 10% of their high school class, 30% were in the next 10% , and the remaining 15% were below the top 20%. Of these students, 95%, 80%, and 20% were passing this course, respectively. If a randomly selected student is failing, then what is the probability that this student was below 20% of his or her high school class
Answers
To find the probability that a randomly selected student who is failing was below 20% of their high school class, we need to use conditional probability. Given the information provided about the distribution of students in different percentile ranges and their passing rates, we can calculate the desired probability.
Let's denote the events as follows:
A: Student is in the bottom 20% of their high school class
B: Student is failing the course
We are interested in finding P(A|B), which represents the probability that a student is in the bottom 20% of their high school class given that they are failing the course.
Using Bayes' theorem, we have:
P(A|B) = (P(B|A) * P(A)) / P(B)
From the given information, we know that P(B|A) = 20% (the failing rate for students below the top 20% of their high school class), P(A) = 15% (the proportion of students below the top 20%), and P(B) can be calculated as follows:
P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)
= 0.20 * 0.15 + 0.80 * (1 - 0.15)
= 0.03 + 0.68
= 0.71
Substituting these values into Bayes' theorem, we can find the probability P(A|B).

What are the coordinates of the last point?On the image we can see an equilateral triangle.
This means that if we draw a vertical line that passes through the top vertex (the one located at (a, c)) that line divides evenly the triangle.
Now, first, notice that point N is on the horizontal axis, then it's y-value must be zero, then we can write:
N(x, 0)
Now, because of the first statement, if x = a reaches the midpoint of the triangle, then the last vertex is at x = 2a

The integral for the area of the surface generated by revolving f(x) = 2x³ + 5x on [1, 4] about the g-axis: is \(\[\int_{1}^{4}{2π(2x^3 + 5x) \sqrt {1 + (6x^2 + 5)^2} dx}\\).
To find the integral for the area of the surface generated by revolving the function
f(x) = 2x³ + 5x on [1, 4] about the g-axis, we use the formula:
\(\[\int_{{}}^{{}}{2πf(x) \sqrt {1 + f'(x)^2} dx}\\)
Where f(x) = 2x³ + 5x and
f'(x) is the derivative of f(x).
Derivative of f(x) = 2x³ + 5x
We use the power rule to differentiate f(x).
Therefore:f'(x) = 6x² + 5
We need to use the formula below to get the integral for the area of the surface generated by revolving f(x) = 2x³ + 5x on [1, 4] about the g-axis:
\(\[\int_{{}}^{{}}{2πf(x) \sqrt {1 + f'(x)^2} dx}\\)

The amplitude of the graphs of the sine and cosine functions is.
Answers
The amplitude of the graphs of the sine and cosine functions is the maximum value of the function.
In trigonometry, the amplitude of a sine or cosine function determines the maximum distance between the graph of the function and its central axis (usually the x-axis). It represents the magnitude of oscillation or the maximum displacement from the equilibrium position. The amplitude is always positive and can be identified by looking at the highest and lowest points of the graph. For both the sine and cosine functions, the amplitude is equal to the absolute value of the coefficient of the trigonometric term. For example, in the function y = Asin(x), the amplitude is A, and in the function y = Bcos(x), the amplitude is B. The larger the amplitude, the more stretched or compressed the graph becomes vertically.

By using the concept of testing of hypothesis, it can be calculated that
The required test statistic is t = 0.918
What is testing of hypothesis?
Suppose, there is a hypothesis and there is a data at hand. Testing of hypothesis is a method of inferencing which is used to decide whether the given hypothesis is true or not based on the statistical data given
From the table attached here, it can be calculated that
\(\bar{x}_{2012}=365.4667\\s^{2}_{2012}=27133.66364\\\bar{x}_{2013}=331.775\\s^{2}_{2013}=29750.53782\\n_{2012}=45\\n_{2013}=40\\\)
So the test statistic t is
\(\large t=\frac{\bar{x}_{2012}-\bar{x}_{2013}}{\sqrt{\frac{s^{2}_{2012}}{n_{2012}}+\frac{s^{2}_{2013}}{n_{2013}}}}\)
\(t=\frac{365.4667-331.775}{\sqrt{\frac{27133.66364}{45}+\frac{29750.53782}{40}}}\)
\(t \large =\frac{33.6917}{36.6978711}\)
t = 0.918
The value of the test statistic is 0.918

Fill in the blank with an appropriate word, phrase, or symbol(s). The number of regions created when constructing a Venn diagram with three overlapping sets is The number of regions created when constructing a Venn diagram with three overlapping sets is 8 3 6
Answers
The number of regions created when constructing a Venn diagram with three overlapping sets is 8.
In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.
When three sets overlap, there are different combinations of elements that can be present in each region.
For three sets, the number of regions can be calculated using the formula:
Number of Regions = 2^(Number of Sets)
In this case, since we have three sets, the formula becomes:
Number of Regions = 2^3 = 8
So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.
Each region represents a unique combination of elements belonging to different sets.
These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.
Therefore, the correct answer is 8.
