Answer: The type of criminal punishment used before prisons were made were various measures adopted by different society but that which was prominent among these societies were exile(where someone is banished from an environment and sent far away with no promises of them returning), flogging, public humiliation.
Explanation:
1) The type of criminal punishment used before prisons were made were various measures adopted by different society but that which was prominent among these societies were exile(where someone is banished from an environment and sent far away with no promises of them returning), flogging, public humiliation.
These punishment's have influenced the modern day of philosophy by not making us know how people are really punished.
2) Today's prison are buildings which are fenced and well secured against the prisoners escaping, having guards guide them always.
3) Prisons serve the purpose of excluding criminals from the society, so residents of society would know that their is a result for bad behavior.
4) Private prison are used to administer to special cases, either highly criminal or special for a particular reason.
5) They are a few of them; they are being harmed by prisoners, they are faced with being antisocial due to they spend most of their time in prisons, especially when there is no shift or rotation of staff
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
9.6 10.3 10.4 10.4
10.2 10.1 10.5 10.3

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]

(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]

Ghana colonial master were called
Answer:
general Abu Bakar Ibn Umar
John Stuart Mill proposed the "harm principle," which basically is the idea that every individual should: a. be controlled by social institutions at all times to limit his/her ability to do harm. b. be imprisoned for life if they harm others or themselves. c. have the utmost freedom over their own actions unless they harm others. d. limit their behavior to that which is not harmful to any living thing.
Answer:
C. have the utmost freedom over their own actions unless they harm others.
Explanation:
The harm principle by stuart is the idea that people are free and have the right to act in whatever way them deem fit except what they do brings others to harm. Anything that can cause others harms is wrong and very wrong that the state can get involved to make sure that such does not occur again.
This idea is one tenet of liberalism, which is a philosophy in political science. This was proposed by John stuart Mill.
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.

Answer:
Subgoals.
Explanation:
Goal is a term used to describe the process of developing personal rules, acts, objectives and translating them into courses of action or an action plan.
This ultimately implies that, goal is a strategic technique used by various individuals or organizations to make an aggregate plan for either a short-term or long-term activities and action.
Also, subgoals are series of plans initiated and established based on main goals. Thus, subgoals are lesser goals that are an integral part of a greater goal.
