Answer:
D. mean is 41.33, and standard deviation is 14.89
Explanation:
Given the data set: 61, 32, 33, 45, 29, 62, 22, 44, 54, 26, 28, 60 of 12 winners.
i. The mean of the data set = \(\frac{sum of data set}{number of data set}\)
= \(\frac{61 + 32 + 33 + 45 + 29 + 62 + 22 + 44 + 54 + 26 + 28 + 60}{12}\)
= \(\frac{496}{12}\)
= 41.3333
The mean of the data set = 41.33
ii. Standard deviation = \(\sqrt{\frac{Sum(x_{i} - U) ^{2} }{N} }\)
Where: \(x_{i}\) is the value of each data set given, U is the mean, N is the number of data set.
Sum (\(x_{i}\) - U) = \((61 - 41.33)^{2}\) + \((32 - 41.33)^{2}\) + \((33 - 41.33)^{2}\) + \((45 - 41.33)^{2}\) + \((29 - 41.33)^{2}\) + \((62 - 41.33)^{2}\) + \((22 - 41.33)^{2}\) + \((44 - 41.33)^{2}\) + \((54 - 41.33)^{2}\) + \((26 - 41.33)^{2}\) + \((28 -41.33)^{2}\) + \((60 - 41.33)^{2}\)
= 386.91 + 87.05 + 69.39 + 13.47 + 152.03 + 427.25 + 373.65 + 7.13 + 160.53 + 235.01 + 177.69 + 348.57
= 2438.68
Standard deviation = \(\sqrt{\frac{2438.68}{12} }\)
= 14.26
Therefore, the statistics mean is 41.33 and standard deviation is 14.89

The financial planning specialist would like additional data for any year showing more than a $ 15,000 median salary increase from the previous year for a master's degree . Which years data would be needed , if any ?
Based on the data, the financial planner would need information on salary increases for at least 10 years prior to the year he wants to assess.
What data is needed to establish the average salary increase?To establish the average salary increase of a person, we must know what their salary increase has been during the previous years. According to the above, the more previous data we have, the more accurate the calculation would be.
However, having at least 10 data is enough. In this case, when we have all the data, we must find the difference between the salaries for each year and then add and divide by the amount of data we have to establish the value of the increase.

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.

What is the orbital path of the planets?Every planet has an elliptical orbit, with the Sun at one of its two foci. A line between a planet and the Sun sweeps out the same amount of space over the same amount of time. A planet's semi-major axis is precisely proportional to the cube of its orbital period, which is squared.The solar system's planets, comets, asteroids, and other celestial bodies revolve around the sun. The majority of solar system objects travel along or very near a hypothetical flat surface.

3 Very little in the way of progress came from the Seneca Falls Declaration, although it would serve
for the next seventy years as the goal for which the suffrage movement strove. Women's suffrage
and nearly all of the other reforms of this era were swallowed up by the single issue of slavery and
its abolition, and women did not receive the right to vote until the adoption of the Nineteenth
Amendment to the Constitution in 1920.
According to the passage, what is the relationship between the movement for women's rights
and the abolition of slavery?
Only a few women became involved with both of these concerns because they were too committed to their
housework.
The movement for women's rights received less attention at the time because many people were more
interested and involved in the slavery issue.
The abolition of slavery became more important to most of the women than the issue of their rights.
Women were not allowed to attend any meetings where the issue of slavery was to be discussed.
The correct answer is B. The movement for women's rights received less attention at the time because many people were more interested and involved in the slavery issue.
Explanation:
The passage explains the issue of slavery and the struggle for abolition prevailed over women's movement and any other movement of the time. This is stated in "Women's suffrage ... were swallowed up by the single issue of slavery and its abolition." Moreover, the author explains due to the importance of the abolition over women's suffrage, abolition occurred before women were given the right to vote. In this context, abolitIon and women's right are related because women's right received less attention during the time as the focus was on abolition (option B.)

The data represent the time, in minutes, spent reading a political blog in a day. Construct a frequency distribution using 5 classes . In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency?
13 18 11 18 7
19 6 10 12 7
14 17 18 6 16
18 10 1 0 15
complete the table starting with lowest class limit
class frequency midpoint r.frequency c. frequency
The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.
To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.
First, we find the range of the data:
Range = Maximum value - Minimum value
Range = 19 - 0
Range = 19
To determine the class width, we divide the range by the desired number of classes:
Class width = Range / Number of classes
Class width = 19 / 5
Class width ≈ 3.8
Now, we can construct the frequency distribution table:
Class Frequency Midpoint R. Frequency C. Frequency
0 - 3.8 2 1.9 2/20 = 0.1 2
3.8 - 7.6 4 5.7 4/20 = 0.2 6
7.6 - 11.4 4 9.5 4/20 = 0.2 10
11.4 - 15.2 3 13.3 3/20 = 0.15 13
15.2 - 19 7 17.1 7/20 = 0.35 20
By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

Diploid
Genetic variability
Haploid
Meiosis
Answer:
option d Meiosis
Explanation:
Term Meaning
Gamete A sex cell (in humans: sperm for males, and eggs for females)
Meiosis A two-step process of cell division that is used to make gametes (sex cells)
Crossing over Process in which homologous chromosomes trade parts
Interphase Phase of the cell cycle where the cell grows and makes a copy of its DNA
Homologous chromosomes Set of chromosomes (one from each parent), that are very similar to one another and have the same size/shape
Sister chromatids Two halves of a duplicated chromosome
Diploid (2n) Cell that contains two sets of homologous chromosomes
Haploid (n) Cell that contains only a single set of genes
Meiosis
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
Stages of meiosis
Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

All rules began with “Do not…”. Ms. Adam’s then read over all 20 rules. By rule 10, 50% of her students lost interest and were not paying attention (i.e. looking out the window, doodling, opening and closing books on their desks, etc.). By rule 15, 90% of the class lost interest. When Ms. Adam’s finished reading all 20 rules, she noticed that some students were already breaking a few rules, many would not make eye contact with her and most ignored her when she quickly transitioned the students to the next activity- math (which had nothing to do with the rules).

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 .

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
The 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer is approximately 1680.9 pounds to 1719.1 pounds. The lower limit is 1680.9 pounds, and the upper limit is 1719.1 pounds.
To calculate the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = sample mean ± (critical value * standard deviation / √sample size)
The critical value corresponds to the desired level of confidence and the sample size. For a 95% confidence level and a sample size of 90, the critical value is approximately 1.96 (obtained from the standard normal distribution).
Substituting the given values into the formula, we have:
Confidence Interval = 1700 ± (1.96 * 92 / √90)
Calculating the values:
Confidence Interval = 1700 ± (1.96 * 92 / √90)
≈ 1700 ± (1.96 * 92 / 9.4868)
≈ 1700 ± 19.12
Rounding to one decimal place, we get:
Confidence Interval ≈ (1680.9, 1719.1)
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer is approximately 1680.9 pounds to 1719.1 pounds. The lower limit is 1680.9 pounds, and the upper limit is 1719.1 pounds.

A research institute poll asked respondents if they felt vulnerable to identity theft in the poll n=1025 and x=549 who said yes use a 95% confidence level
The best point forecast of the population proportion is p = 0.6157, the margin of error for the poll is E = 0.0414, and the confidence interval is CI = 0. (0.5743, 0.6571)
What is a poll?Opinion polls are typically designed to represent a population's opinions by asking a series of inquiries and then trying to extrapolate broad generalizations in ratio or within confidence intervals. A pollster is an individual who conducts polls.
We have been given;
n = 916 people participated in the poll.
x = 564 is the number of people who said yes.
The formula would yield the population proportion;p = x/n
p = 564/916
p = 0.6157
The formula for the margin of error is;E = (z_α/2)√(p^(1 - p^)/n)
Where;
(z_α/2) is the critical value at the given confidence level.
Critical value z_α/2 for confidence level of 99% from tables is: 2.576.
So,
E = 2.576√(0.6157(1 - 0.6157)/916)
E = 0.0414
Formula for the confidence interval is;CI = p^ ± (z_α/2)√(p^(1 - p^)/n)
From B it can be known that
(z_α/2)√(p^(1 - p^)/n) = 0.0414
So,
CI = 0.6157 ± 0.0414
CI = (0.6157 - 0.0414), (0.6157 + 0.0414)
CI = (0.5743, 0.6571)
Thus, the answer for part a, b, and c is p = 0.6157, E = 0.0414, and CI = (0.5743, 0.6571) respectively.
