Suppose you wanted to find out what percentage of upper class Western High students' own cars? You decided to do a stratified sample based on the junior and senior population at school. There are 800 seniors and 1,200 juniors at Western for a total of 2000 students. How many juniors and seniors would you survey if you were to take a sample of 100 students. Hint - This requires a little math - First figure out the percentages of each subgroup to the total number of upper-class students.​

Answers

Answer 1

Answer:

Samples 40 seniors and 60 juniors would be surveyed.

Explanation:

Stratified sample refers to a sample that is obtained through a stratified sampling method which divides the total population of interest into smaller groups or strata.

The basis that is used in forming the strata are some common characteristics that the population data have.

From the question, the strata are the seniors and the juniors. The number of juniors and seniors that would be surveyed to take a sample of 100 students can be obtained based on the percentage contribution of each stratum to the total population as follows:

Number of senior population = 800

Number of junior population = 1,200

Total number of studnts = 2,000

Sample to survey = 100

Percentage of senior population in the total population = (Number of senior population / Total number of students) * 100 = (800 / 2,000) * 100 = 0.40 * 100 = 40%

Percentage of juniors population in the total population = (Number of junior population / Total number of students) * 100 = (1,200 / 2,000) * 100 = 0.60 * 100 = 60%

Number of sample of seniors = Percentage of senior population in the total population * Sample to survey = 40% * 100 = 40 seniors

Number of sample of juniors = Percentage of juniors population in the total population * Sample to survey = 60% * 100 = 60 juniors

Therefore, samples 40 seniors and 60 juniors would be surveyed.

In exchange for their passage to the Americas, the servants agreed to work for a set number of years, typically ranging from four to seven years. During their term of service, the indentured servants received basic necessities such as food, clothing, and shelter from their masters. Once their term was complete, they were granted their freedom and were no longer bound by the indenture. Some servants were also given land and other benefits as part of their agreement. However, it is important to note that not all indentured servants were able to achieve economic success or acquire land after their servitude.

In many countries, citizens are required to serve in the military for a year or more. Do you believe the United States should institute a similar practice? Why or why not? Use specific reasons and examples to support your answer. Group of answer choices

Answers

Answer:

1. Violates Free Will

One of the arguments raised against mandatory military service is that it violates people’s rights to exercise free will. No one has the final say whether they should participate or not in the military training and enter the army since it is a compulsory mandate implemented throughout the country.

2. Interferes with Other Forms of Education

Mandatory military service typically drafts young men (and women) when they are at the peak of their learning ability (18 years old). This delays individuals’ pursuit for higher education as well as their entry into the into the civilian labor market, reducing returns to human-capital investments as a result.

3. Put Young People’s Lives at Risk

Though you might not like to think about it, part of the process is risking young people lives at risk. Casualties don’t just happen in actual combat or in the battle field but also during training and the like. Mandatory military service, which normally enlists able-bodied young people, put the next generation to serious harm and, at worst, death.

Mediavine

4. Compromises the Quality of Military Service

Unlike voluntary soldiers who are willing to undergo rigorous training and serve the country for a long time in the military, draft soldiers often lacks the necessary experience and preparedness, providing low combat skill quality when the time comes they are sent to war. This could lead to high casualty rate among soldiers drafted under compulsory military service.

5. Not Everyone Is Fit for It

Mandatory military service requires every citizen to join and serve in the armed forces, but not everyone is cut out for it. Whether it is mental issue, physical issue, or psychologically issue, not everyone is fit to meet the physical, mental and emotions demands of the job. Factors like anxiety, depression and the like should be carefully considered. Potentially killing someone is something that every person who was drafted in the military struggles with in their own way. A study conducted by the Anxiety and Depression Association of America showed that approximately 40,000 military members who returned from war in Iraq and Afghanistan suffered from post-traumatic stress disorder (PTSD). And that rate is three times higher among those who were deployed in combat than those who were non-deployed.

Explanation:

My answer would be yes. The sacrifices made by members of the military for their nation can be understood and appreciated by the public. And all of them have the power to unite people, particularly in the face of a cultural or political challenge from another country.

Why should citizens be required to serve in the military?

Improved civic education may be more beneficial on the civilian side. More serious efforts may be made to demystify the military by informing the public about it as a vocation, its skills, and its legitimate place in society. Even if it would not directly motivate more individuals to enlist, this would undoubtedly increase the general public's awareness of the military and lessen America's toxic idolatry of military might.

It would be far preferable to impose mandatory universal service in the military, civilian, public, or nonprofit sectors if the ultimate objective is to rekindle Americans' desire to serve their nation and rethink citizenship as endowing people with duties in addition to rights.
