Answer:
Atlanta is known as the “the cradle of the Civil Rights Movement” for good reason. From 1940 to 1970, the city became the epicenter for the movement as black leaders fought for voting rights, access to public facilities and institutions, and economic and educational opportunities for African Americans. As the Civil Rights Movement grew, Black leaders in Georgia organized around churches and other community-based institutions. They organized protests, rallies and other events to fight segregation. ... White supremacy flared in the 1950s as supporters of segregation rallied.

Which of the following could be a disadvantage of living under an authoritarian government? OA. The education systems are usually very strict. OB. Citizens have very few rights and freedoms. OC. Citizens must help create government policies. OD Government leaders have little authority.
Answer:
B. Citizens have very few rights and freedoms.
Explanation:
An authoritarian government is also known as dictatorship and it can be defined as a type of government in which an individual who is a sole administrator is responsible for controlling, managing and directing the affairs of the particular country. Therefore, they do not listen to anyone else but rather are saddled with the decision-making responsibilities without consulting any other government official.
The disadvantage of living under an authoritarian government that citizens have very few rights and freedoms.
Generally, citizens living in a country or society that practices an authoritarian government are usually lacking in individual freedoms because the supreme leader ignores rules limiting his or her power with respect to the citizens and institutions.
Some examples of authoritarian government around the world are the government of Idi Amin of Uganda, Adolf Hitler of Nazi Germany, Joseph Stalin of the Soviet Union etc.
A researcher performs an experiment to test the hypothesis that the hormone oxytocin plays an important role in falling in love. In this experiment the researcher measures the oxytocin levels of men and women, and then introduces them to complete strangers. An hour later she asks the subjects of the experiment whether or not they would like to go out on a date with the person to whom they were introduced an hour previously. She finds that the people with the high oxytocin levels were more likely to want to go out on that date than people with low oxytocin levels.
A. Men and Women
B. Whether or not people would like to go out on a date
C. None for this experiment
D. Levels of oxytocin in each individual
For each letter, match the following:
1) Experimental Group
2) Control Group
3) Independent Variable
4) Dependent Variable
Answer:
The answers are:
1) Experimental Group = Men and Women
2) Control Group = None for this experiment
3) Independent Variable = Levels of oxytocin in each individual
4) Dependent Variable = Whether or not people would like to go out on a date
Explanation:
There are some terms associated with scientific experiments. Let me explain each of the terms as captured in the question:
1. Experimental Group: The experimental group in scientific research refers to the group on which an intervention or a factor causing changes to be studied is carried out. In this example, the men and women whose oxytocin levels were measured forms the experimental group, because they fulfilled certain criteria (having certain measurable level of oxytocin) hence they are qualified for studies to be carried out on them.
2. Control Group: The control group is absent in this experiment, but ideally it is the group that possesses every other similar characteristic as the experimental group except for the factor causing the change that is being studied. They serve as a baseline to ensure that the changes noticed are caused by the experimental factor alone.
3. Independent Variable: These are variables whose value are predetermined or preconceived before the start of the experiment. They are the variables whose presence cause an outcome that is measured. In this example, levels of oxytocin are the independent variable.
4. Dependent Variable: the dependent variable is the variable that take on values/outcomes based on the effect of the independent variable.The dependent variables are not under the direct manipulation of the experimenter but have their outcome from the manipulation of the independent variable.

How would I describe a Tornado and what causes this type of tornado weather ?
Answer:
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction.

The hyperfocus on crime among athletes is limited to what two sports?
The correct answer to this open question is the following.
Unfortunately, you did attach further context or references.
However, we can comment on the following.
The hyperfocus on crime among athletes is limited to these two sports: football and basketball.
The reason why is that these two sports produce too many "stars" that have too much notoriety for their conduct and behaviors. Some of the athletes that participate in these professional sports got too much attention from the media and the public and are considered famous. This popularity often produces that they lost the ground and act in incongruent ways, many times making the worts decisions that impact their careers by the mistakes they make.
As the public figures they are, their behavior immediately makes the news, and their poor judgment often brings negative consequences to their careers.
In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metallization. The etch rate is an important characteristic of this process and known to follow a normal distribution. Two different etching solutions have been compared using two random samples of 10 wafers for each solution. Assume the variances are equal. The etch rates are as follows (in ml per minute):
Solution 1 Solution 2
9.8 10.4 10.2 10.0
9.4 10.3 10.6 10.2
9.3 10.0 10.7 10.7

Answer:
[tex](a)[/tex] [tex]\bar x_1 = 9.94[/tex]
[tex](b)[/tex] [tex]x_2 = 10.4[/tex]
[tex](c)[/tex] [tex]\sigma_1 = 0.395[/tex]
[tex](d)[/tex] [tex]\sigma_2 = 0.231[/tex]
(e) There is sufficient evidence to reject the claim that the mean etch rate is the same for both solutions
[tex](f)[/tex] [tex]-0.75644 < \mu_1 - \mu_2 < -0.1556[/tex]
Explanation:
Given
Solutions 1 and 2
Solving (a): Mean of solution 1
For Solution 1, we have the following data:
[tex]9.8\ 10.4\ 9.4\ 10.3\ 9.3\ 10.0\ 9.6\ 10.3\ 10.2\ 10.1[/tex]
The sample mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
Where
[tex]n_1 = 10[/tex]
So, we have:
[tex]\bar x_1 = \frac{9.8+ 10.4+ 9.4+ 10.3+ 9.3+ 10.0+ 9.6+ 10.3+ 10.2+ 10.1}{10}[/tex]
[tex]\bar x_1 = \frac{99.4}{10}[/tex]
[tex]\bar x_1 = 9.94[/tex]
Solving (b): Mean of Solution 2
For Solution 1, we have the following data:
[tex]10.2\ 10.0\ 10.6\ 10.2\ 10.7\ 10.7\ 10.4\ 10.4\ 10.5\ 10.3[/tex]
The sample mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
Where
[tex]n_2 = 10[/tex]
So, we have:
[tex]x_2 = \frac{10.2+ 10.0+ 10.6+ 10.2+ 10.7+ 10.7+ 10.4+ 10.4+ 10.5+ 10.3}{10}[/tex]
[tex]x_2 = \frac{104}{10}[/tex]
[tex]x_2 = 10.4[/tex]
Solving (c): Sample Standard Deviation of solution 1
This is calculated as:
[tex]\sigma_1 = \sqrt{\frac{\sum (x-\bar x_1)^2}{n_1-1}}[/tex]
This gives:
[tex]\sigma_1 = \sqrt{\frac{(9.8 - 9.94)^2+ (10.4- 9.94)^2+ (9.4- 9.94)^2+................+ (10.2- 9.94)^2+ (10.1- 9.94)^2}{10 - 1}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{1.404}{9}}[/tex]
[tex]\sigma_1 = \sqrt{0.156}[/tex]
[tex]\sigma_1 = 0.39496835316[/tex]
[tex]\sigma_1 = 0.395[/tex] --- approximated
Solving (d): Sample Standard Deviation of solution 2
This is calculated as:
[tex]\sigma_2 = \sqrt{\frac{\sum (x-\bar x_2)^2}{n_2-1}}[/tex]
So, we have:
[tex]\sigma_2 = \sqrt{\frac{(10.2 - 10.4)^2+ (10.0 - 10.4)^2+ (10.6 - 10.4)^2+ (10.2 - 10.4)^2+.......................+ (10.3 - 10.4)^2}{10-1}}[/tex]
[tex]\sigma_2 = \sqrt{\frac{0.48}{9}}[/tex]
[tex]\sigma_2 = \sqrt{0.05333333333}[/tex]
[tex]\sigma_2 = 0.23094010766[/tex]
[tex]\sigma_2 = 0.231[/tex]
Solving (e): Test the hypothesis
[tex]H_0: \bar x_1 = \bar x_2[/tex]
[tex]H_1: \bar x_1 \ne \bar x_2[/tex]
Start by calculating pooled standard deviation
[tex]s_p = \sqrt{\frac{(n_1 - 1)*\sigma_1^2 + (n_2 - 1)*\sigma_2^2}{n_1 + n_2 -2}[/tex]
[tex]s_p = \sqrt{\frac{(10 - 1)*0.395^2 + (10 - 1)*0.231^2}{10+ 10-2}[/tex]
[tex]s_p = \sqrt{\frac{1.884474}{18}[/tex]
[tex]s_p = \sqrt{0.104693}[/tex]
[tex]s_p = 0.324[/tex]
Calculate test statistic
[tex]t = \frac{\bar x_1 - \bar x_2}{s_p\sqrt{\frac{1}{n_1} + \frac{1}{n_2}}}[/tex]
[tex]t = \frac{9.94 - 10.4}{0.324 * \sqrt{\frac{1}{10} + \frac{1}{10}}}[/tex]
[tex]t = \frac{-0.46}{0.324 * \sqrt{0.2}}[/tex]
[tex]t = \frac{-0.46}{0.324 * 0.4472}[/tex]
[tex]t = \frac{-0.46}{0.1448928}[/tex]
[tex]t = -3.175[/tex]
Calculate the degree of freedom
[tex]df = n_1 + n_2 - 2[/tex]
[tex]df = 10+10 - 2[/tex]
[tex]df = 18[/tex]
The p value is the in the column title of the student t distribution in row 18
[tex]p = 002621[/tex]
The p value is less than the significance level (0.05).
i.e.
[tex]p < 0.05[/tex]
So: Reject the null hypothesis
Solving (f): 95% two-sided confidence interval
[tex]c = 95\%[/tex]
Calculate the degree of freedom
[tex]df = n_1 + n_2 - 2[/tex]
[tex]df = 10+10 - 2[/tex]
[tex]df = 18[/tex]
Calculate [tex]\alpha[/tex]
[tex]\alpha = (1 - c)/2[/tex]
[tex]\alpha = (1 - 95\%)/2[/tex]
[tex]\alpha = (0.05)/2[/tex]
[tex]\alpha = 0.025[/tex]
Using student t distribution
[tex]t_{\alpha/2} = 2.101[/tex]
Calculate margin of error (E)
[tex]E = t_{\alpha/2} * s_p * \sqrt{\frac{1}{n_1} + \frac{1}{n_2}}[/tex]
[tex]E = 2.101 * 0.324 * \sqrt{\frac{1}{10} + \frac{1}{10}}[/tex]
[tex]E = 2.101 * 0.324 * \sqrt{0.2}[/tex]
[tex]E = 0.3044[/tex]
The boundaries of the confidence are:
[tex](\bar x_1 - \bar x_2) -E[/tex] [tex]= (9.94- 10.4) - 0.3044 = -0.7644[/tex]
[tex](\bar x_1 - \bar x_2) + E[/tex] [tex]= (9.94- 10.4) + 0.3044 = -0.1556[/tex]
The confidence interval is:
[tex]-0.75644 < \mu_1 - \mu_2 < -0.1556[/tex]
