You have 4 numbered tags in a bag { 1,3,5,7}. You will draw out two without replacement.
a) find the mean of the population
b) List all possible samples of two and calculate the mean of each sample
c) Calculate the sample mean of all your sampling distribution. Compare to your answer with the population mean.
Answer:
Explanation:
a) The mean of the population is given by:
Mean = (1 + 3 + 5 + 7) / 4 = 4
Therefore, the mean of the population is **4**.
b) There are six possible samples of two that can be drawn from the population:
{1,3}, {1,5}, {1,7}, {3,5}, {3,7}, {5,7}
The mean of each sample is:
{1,3}: (1+3)/2 = 2
{1,5}: (1+5)/2 = 3
{1,7}: (1+7)/2 = 4
{3,5}: (3+5)/2 = 4
{3,7}: (3+7)/2 = 5
{5,7}: (5+7)/2 = 6
Therefore, the means of all possible samples are:
2, 3, 4, 4, 5, 6
c) The sample mean of all possible samples can be calculated as follows:
Sample mean = (2 + 3 + 4 + 4 + 5 + 6) / 6 = 24 / 6 = 4
The sample mean is equal to the population mean. This is because the sample size is small and all possible samples have been considered. In general, as the sample size increases and more samples are considered, the sample mean will approach the population mean .
I hope this helps! Let me know if you have any other questions or if there is anything else I can help you with.

clarify why the Bill of rights provides for section 36 which sets limits to the exercise of all the rights in south Africa
Answer:
The purpose of Section 36 of the Bill of Rights is to ensure that the exercise of individual rights is balanced against the greater interests of society, and that any limitations on those rights are reasonable and justifiable in a democratic society.
Explanation:
Section 36 of the South African Constitution is known as the "Limitation Clause," and it sets limits on the exercise of all rights enshrined in the Bill of Rights. The reason for this clause is to ensure that the exercise of individual rights does not unjustifiably infringe upon the rights of others or the public interest.
The Bill of Rights in the South African Constitution is considered one of the most progressive in the world, as it guarantees a range of civil, political, economic, social, and cultural rights to all citizens. However, it also recognizes that there may be circumstances where the exercise of those rights may need to be limited in the interests of society as a whole.
Section 36 allows for the limitation of rights in certain situations, but only if the limitation is reasonable and justifiable in an open and democratic society based on human dignity, equality, and freedom. This means that any limitation on a right must be for a legitimate purpose and must be proportional to the importance of that purpose.
For example, the right to freedom of expression may be limited if that expression promotes hate speech or incites violence. The right to property may be limited if it is necessary to promote land reform or address historical injustices. However, any limitation must be necessary, reasonable, and justifiable in a democratic society.
In summary, the purpose of Section 36 of the Bill of Rights is to ensure that the exercise of individual rights is balanced against the greater interests of society, and that any limitations on those rights are reasonable and justifiable in a democratic society.
Answer:
In addition, the Constitution provides a General Limitation Clause at Section 36, which provides for all rights in the Bill of Rights to be limited in terms of law of general application and that "limitations must be reasonable and justifiable in an open and democratic society based on human dignity, equality, and ...

Produce a scatterplot of the provided dataset. Make sure to include a title and to assign labels to your axis. Edit the graph (i.e., set the background to transparent; borders to transparent; add greyed out grid lines) and add a regression line. Comment on the noted relationship (e.g., is it positive; is it negative?). What else can be said about the relationship concerning time spent on phone and battery life? If we were to break up the scatterplot into 4 quadrants; what would data points in the top left, bottom left, top right and bottom right say about the relationship concerning time spent on phone and battery life? For this example, in which quadrant(s) do the data points lie.)
The scatterplot will show that there is a negative relationship between time spent on the phone and battery life remaining.
How to explain the scatterplotThe scatterplot shows a clear negative relationship between time spent on the phone and battery life remaining. As time spent on the phone increases, battery life remaining decreases. The regression line also shows a negative slope, which confirms this relationship.
In bottom right, data points in this quadrant represent times when the battery life was low and the time spent on the phone was high. This is the most likely quadrant for data points to fall in, as it represents times when the phone was being used heavily.
In this example, all of the data points fall in the bottom right quadrant, which confirms that there is a negative relationship between time spent on the phone and battery life remaining.

What is the lower class boundary for the first class?
The lower class boundary of the fish is the average of the lower limit of the class in question and the previous upper limit
The lower class boundary of the first class is 99.5
How to determine the lower class boundary?From the complete question, we have the first and the second classes to be:
100 - 114
115 - 129
The difference between the upper limit of a class and the lower limit of the next class is 1. i.e. 115 - 114 = 1
Half of 1 is 0.5
The lower class limit of the first class is 100
Subtract 0.5 from 100 to determine the lower class boundary of the first class
Lower = 100 - 0.5
Evaluate the difference
Lower = 99.5
Hence, the lower class boundary of the first class is 99.5

2. Suppose that all possible n = 50 samples are selected from a population. How would the mean,
standard deviation, and shape of the resulting sampling distribution compare to a sampling
distribution based on all possible n= 100 samples?
Using the Central Limit Theorem, it is found that the mean and the shape would remain the same, while the standard deviation would be multiplied by the square root of 2.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem:
The sample size would remain above 30, hence the shape would still be normal.The mean does not depend on the sample size, hence it would remain constant.The standard deviation is inversely proportional to the square root of the sample size, then since the sample size would be divided by 2, the standard deviation would be multiplied by the square root of 2.More can be learned about the Central Limit Theorem at https://brainly.com/question/24663213

what is the vertex of x^2 + 4x - 12
Answer:
\((-2, -16)\\\)
Explanation:
The vertex of a quadratic function which gets plotted as a parabola is either the minimum or maximum (x, y) value of that function.
The following rule applies to finding the x value of the vertex
\(\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:\\y=ax^2+bx+c\:\mathrm{is}\:x_v=-\dfrac{b}{2a}\)
The equation is
\(y=x^2+4x-12\)
\(\textrm {Here }\\a = 1, b = 4, c= -12\\\\\)
\(So\; x_v, \textrm{ the x value of the vertex } = -\dfrac{4}{2\cdot \:1} = -2\\\\\textrm {Plug this value of x into the equation to find the y-value of the vertex}\\\)
\(y_v=\left(-2\right)^2+4\left(-2\right)-12\\\\\\y_v = 4 -8 - 12 = -16\\\\\)
\(\mathrm{Therefore\:the\:parabola\:vertex\:is}\\(-2, -16)\)
2. In its first year, “DM Trading” had the following experience: Unit selling price birr 100 Sales 50,000 units Total fixed cost birr 400,000 TVC birr 3,000,000 Required: a) Develop TR, TC and profit functions for the company in terms of quantity b) Find the breakeven point in terms of quantity and sales volume.
a) The total revenue (TR) function can be calculated by multiplying the unit selling price by the quantity sold.
In this case, TR = 100 * Q, where Q represents the quantity sold. The total cost (TC) function consists of the sum of fixed costs (FC) and total variable costs (TVC). Given that the fixed costs are 400,000 birr and the TVC is 3,000,000 birr, the TC function can be expressed as:TC = FC + TVC = 400,000 + 3,000,000 = 3,400,000 birr.
The profit function (P) can be determined by subtracting the total cost from the total revenue, so P = TR - TC = 100Q - 3,400,000 birr.
b) The breakeven point can be found by setting the profit function equal to zero, as this is the point where total revenue equals total cost.
In this case, 100Q - 3,400,000 = 0. Solving for Q, we find Q = 3,400,000 / 100 = 34,000 units. Therefore, the breakeven point in terms of quantity is 34,000 units. To calculate the sales volume at the breakeven point, we can multiply the breakeven quantity by the unit selling price:Sales Volume = 34,000 units * 100 birr/unit = 3,400,000 birr. Hence, the breakeven point in terms of sales volume is 3,400,000 birr.

In the computer game World of Warcraft, some of the strikes are critical strikes, which do more damage. Assume that the probability of a critical strike is the same for every attack, and that attacks are independent. During a particular fight, a character has 248 critical strikes out of 598 attacks.
Using the z-distribution, the 95% confidence interval for the proportion of critical strikes out of all attacks is given by:
0.3752 < p < 0.4542
What is a confidence interval of proportions?A confidence interval of proportions is given by the following rule:
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which the parameters are described as follows:
\(\pi\) is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The character has 248 critical strikes out of 598 attacks, hence the values of the parameters are given as follows:
\(n = 598, \pi = \frac{248}{598} = 0.4147\)
The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.
The lower bound of the interval is given as follows:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4147 - 1.96\sqrt{\frac{0.4147(0.5853)}{598}} = 0.3752\)
The upper bound of the interval is given as follows:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4147 + 1.96\sqrt{\frac{0.4147(0.5853)}{598}} = 0.4542\)

look at these two triangles triangle b is a reflection of triangle a
Triangle B is a reflection of Triangle A.
Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.
Reflection is a transformation in which a figure is flipped over a line to create a mirror image. In the case of triangles, a reflection would involve flipping the triangle over a line to create a new triangle that is a mirror image of the original.
When Triangle B is a reflection of Triangle A, it means that Triangle B is created by reflecting Triangle A over a line.
The line of reflection is an imaginary line that serves as the axis of symmetry for the reflection. It is a line that each point on Triangle A is reflected across to create the corresponding point on Triangle B.
When Triangle B is a reflection of Triangle A, the corresponding sides and angles of the triangles will be equal in measure. This is because reflection preserves the shape and size of the original figure.
The vertices of Triangle B will be the mirror image of the vertices of Triangle A. For example, if vertex A in Triangle A is reflected to vertex A' in Triangle B, the distance between the line of reflection and vertex A will be equal to the distance between the line of reflection and vertex A'.
Similarly, the angles in Triangle B will be equal in measure to the corresponding angles in Triangle A.
The sides of Triangle B will have the same lengths as the corresponding sides of Triangle A.
Overall, when Triangle B is a reflection of Triangle A, the two triangles will have the same shape and size but will be facing in opposite directions.
By understanding the concept of reflection and the properties of a reflection, we can conclude that Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.
