One of the questions on a survey of 1,000 adults asked if today's children will be better off than their parents. Representative data are shown in the file named childoutlook. A response of yes indicates that the adult surveyed did think today's children will be better off than their parents. A response of no indicates that the adult surveyed did not think today's children will be better off than their parents. A response of not sure was given by 23% of the adults surveyed.

Answers

Answer 1

Answer:

Explanation:

The missing representative data include the file named Childoutlook is an excel spreadsheet showing the response to the survey. The missing file is shown in the document attached below.

From the first question in the attached file below:

a) To find the point estimate, we use the formula:

[tex]\hat p = \dfrac{x}{n}[/tex]

where;

x = number of adult that said "yes" = 240

n = total adults = 1000

[tex]\hat p = \dfrac{240}{1000}[/tex]

[tex]\hat p = 0.24[/tex]

b)

To find the margin of error at 95% confidence interval.

The Margin of Error [tex]M.O.E = Z_{critical} \sqrt{\dfrac{\hat p ( 1- \hat p) }{n}}[/tex]

At 95% C.I ; The level of significance [tex]\alpha[/tex] = 1 - 0.95 = 0.05

The critical value at [tex]Z_{\alpha/2} = Z_{0.05/2}= 1.96[/tex]

Then, the margin of error [tex]M.O.E =1.96 \sqrt{\dfrac{0.24( 1- 0.24) }{1000}}[/tex]

[tex]M.O.E = 1.96 \sqrt { \dfrac{0.1824}{1000}}[/tex]

[tex]M.O.E = 1.96 \sqrt {1.824 \times 10^{-4} }[/tex]

M.O.E =/ 1.96 × 0.013506

The Margin of Error M.O.E = 0.0265

c)

To determine the 95% C.I for the adults who thought that today children will be better than their parents.

i.e.

C.I = [tex]\hat p \pm M.O.E[/tex]

C.I = 0.24 ± 0.0265

C.I = (0.24 - 0.0265, 0.24 + 0.0265)

C.I = (0.2135

, 0.2665

)

C.I = ( 0.214, 0.267)   to 3 decimal places

Era justa la acusación interpuesta contra Sócrates por impiedad no creyendo en los dioses en los que la ciudad cree, sino en otras divinidades nuevas (Es de filosofía pero no me sale esa materia para elegirla así k elegí una random)

Answers

La respuesta correcta para esta pregunta abierta es la siguiente.

Aquí sólo incluiste una afirmación, pero no estás preguntando nada.

¿Tú pregunta es de verdadero o falso? ¿O quieres que hagamos un comentario al respecto?

Varios historiadores comentan que fue justa la acusación interpuesta contra Sócrates por impiedad no creyendo en los dioses en los que la ciudad cree, sino en otras divinidades nuevas.

Estos historiadores afirman que el gran maestro de filosofía, Sócrates, lo que hizo fue invitar a los jóvenes Griegos a que pensaran por sí mismos y contemplaran nuevas alternativas con respecto a la divinidad. Él lo hizo utilizando su famoso método Socrático también conocido como Mayéutica.

Su método fue tan exitoso con los estudiantes que los gobernantes lo vieron como una amenaza y por eso lo acusaron y sentenciaron.

No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law. I NEED A SMALL SUMMARY OF THIS!!

Answers

It is saying that the army can’t demand and force you to accept them and feed them in your own house in war or peace but if you give them consent (permission) then they can.

Answer:

The Third Amendment to the U.S. Constitution reads, no soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law. This basically means that if the owner of the house or property does not give consent, no soldier can stay at their house or property. This amendment was created because of the quartering acts that were part of the British government's rule over the colonies. The Quartering Act required the colonies to feed and house these soldiers. The third amendment gives Americans the freedom to not have to house or care for soldiers unless Americans want to.

Answers

Answer:

He was considered to be the greatest poet.

Explanation:

Virgil was regarded by the Romans as their greatest poet, an estimation that subsequent generations have upheld. His fame rests chiefly upon the Aeneid, which tells the story of Rome’s legendary founder and proclaims the Roman mission to civilize the world under divine guidance.

He was considered to be the greatest poet Virgil’s most significant contribution to Roman society. Thus, option (c) is correct.

What is society?

The term "society" refers to a group of people. The society encompasses various cultures, traditions, and languages. People are similar in the group that is called society. The various communities of people comprise the society. People are similar in their looks and their interactions with each other.

The Romans considered Virgil to be their finest poet, an opinion that has been shared by following generations. The Iliad, which recounts of Rome's mythological origin and proclaims the Roman purpose to reeducate the world under divine direction, is largely responsible for his society.

As a result, he was considered to be the greatest poet Virgil’s most significant contribution to Roman society. Therefore, option (c) is correct.

They hired missionaries to travel around the empire.
PLZ answer fast, im timed!!

Answers

Answer:

B

Explanation:

The correct option is B. The apostles are important in early Christianity because they shared Jesus’s teachings.

Later, in the capital of the Roman Empire, Rome, Peter was executed as a martyr. The apostles later established apostolic sees near the earliest Christian settlements and preached the gospel throughout the ancient world.

What is the importance of the Apostles?

The most brilliant and splendid truths of the Christian religion are outlined in the Apostles' Creed. It inevitably leads our souls to praise and worship God with all of our hearts. The most important facts that allow us to worship God and properly exalt his name are found in the creeds, which also serve as the church's worship manual.

Not just because there are no longer any living apostles, but also since the Church was built on the teaching of the apostles, the apostles' teaching is significant. Paul emphasizes this in Ephesians 2:20 by stating that Christ Jesus Himself is the cornerstone of the Church, which is "built on the foundation of the apostles and prophets."

Rome has limited rainfall during growing seasons.
PLZ hurry fast, im timed!!

Answers

Answer:

Rome has short, mild winters.

The correct option is A. Rome has short, mild winters which best describes Rome’s climate.

The climate in Rome and the surrounding area is the Mediterranean, with pleasant winters and warm to scorching summers. The climate of Rome is classified as warm-temperate subtropical by the Troll-Paffen climatic classification system.

Why does Rome get so hot?

Rome has a warmer climate overall, especially in the winter, even though New York and Rome share the same latitude and receive the same amount of energy from the sun. Due to "stationary waves," which are significant shifts in the airflow with longitude, this occurs.

Rome experiences cold winters and warm, humid summers due to its Mediterranean climate. Lows of 2°C in January and highs of 30°C in July and August are typical temperature ranges. Rainfall is minimal or nonexistent throughout the summer, but it rises to an average of 90mm in November and December.

Thus, Rome's climate is primarily characterized by its brief, warm winters. Rome and the surrounding area experience a Mediterranean climate with mild winters and warm to hot summers.

what is the essence of communication in intersubjectivity/intersubjective human relationship?​

Answers

Answer:

Intersubjective communication highlights that understanding and consensus are essential for the construction of social interaction and social meanings.

Explanation:

The notion of intersubjectivity can be approached from the concept of interaction. It is usually understood by intersubjective communication as the interaction between individuals in relation to a shared real world,which is  physical,social and cultural. As it is usually conceived, then, intersubjectivity is a basically triangular phenomenon, which involves a self, an other and an objective reality that both assume to share, constituting their various subjectivities mutually. Social interaction is the fundamental vehicle for the transmission and dynamic construction of philosophical, scientific, political, cultural and historical knowledge. This implies the active-passive involvement of people in an exchange, where different experiences and actions take place.
