In a certain region, many of the residents are employed by the oil industry. Economists in the region investigated the difference between the salaries of those who work in oil-field jobs and those who work in non-oil-field jobs. Salaries were recorded for a random sample of 84 workers from the 1,200 oil-field workers and a random sample of 72 workers from the 50,000 non-oil-field workers in the region. A 95 percent confidence interval for μO−μN, where μO is the mean salary of all jobs of oil-field workers and μN is the mean salary of all jobs of non-oil-field workers, will be constructed. Have the conditions for inference with a confidence interval been met?

A: Yes, all conditions have been met.

B: No, the data were not collected using a random method.

C: No, the size of at least one of the samples is greater than 10 percent of the population.

D: No, the sample sizes are not large enough to assume the distribution of the difference in sample means is normal.

E: No, the sample sizes are not the same.

Answers

Answer 1

Answer:

The answer is A: Yes, all conditions have been met.

Random: Stated

Independent: None of the samples are greater then 10 percent of total population

Normal: n>30 so its assumed to be normal.

Sample sizes don't have to be the same unless it is a Matched pair test.

a toy car hitting a wall and bouncing back
a toy car rear-ending a toy car that then rear-ends another toy car
two toy cars driving parallel to each other at the same speed
two toy cars driving away from each other at the same speed

Answers

Answer:

a toy car rear-ending a toy car that then rear-ends another toy car

Explanation:

all waves carry energy, and the cars bumping into each other transfers energy from one car the the next. it is like a transverse wave, the wave will go perpendicular like a spring moving up and down, dominos tipping over, or a car hitting another car.

A wave can be typified here by a toy car rear-ending a toy car that then rear-ends another toy car.

What is  a wave?

A wave is a disturbance in a medium that transfers energy. We have to note that waves have a maximum disturbance called an amplitude. We can see an example of a wave when we cause a spring to vibrate.

A typical example of a wave in this case is a toy car rear-ending a toy car that then rear-ends another toy car.

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

Answers

Answer:

Answer: 4,772.8 cm2

Explanation:

The company will need 3,583.2 square inches of paper to make 15 labels.

What is cylinder?

Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.

The formula for circumference is:

Circumference = π × diameter

Circumference = 3.14 × 8in

Circumference = 25.12in

So the label will need to be 25.12 inches long.

The height of the label will be the same as the height of the can, which is 9 inches.

To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:

Total area = length × height × number of labels

Total area = 25.12in × 9in × 15

Total area = 3,583.2 square inches

Thus, the answer is 3,583.2 square inches.

Describe the trend in judicial independence in the United Kingdom between 1990 and 2019. Explain a possible reason for this trend.

Answers

Answer:

The main factors aimed at securing judicial independence

 

The previous section has briefly explained why judicial independence is important for maintaining judges' impartiality and the rule of law. This section now focuses on how judicial independence can be guaranteed in its fundamental aspects (external, internal, institutional and individual independence). Various mechanisms are possible, and a range of examples are provided to encourage debate and develop critical thinking.

Judicial independence is a multifaceted concept. There are different institutional, legal and operational arrangements that in abstracto are designed to ensure judicial independence, and they can work differently depending on the historical, political, legal and social context in which the judiciary operates. Therefore, there is not an ideal model of implementing judicial independence in the sense that one-size-fits-all. Judicial independence is - in more concrete terms - the result of a combination of different conditions, measures, checks and balances, that can vary from one country to another. Every country has to find its own balance.

In some countries, for example, judicial independence is basically secured through a self-governing body or council (composed mainly of judges) which is in charge of all the decisions concerning judges' recruitment/nomination, career, transfer and discipline. This occurs, for example, in France, Italy, Mongolia, Nigeria, Poland, Romania, Spain, and Ukraine. In other countries, such as Kenya, South Africa, India, Germany, Austria, Czech Republic, India, Kenya, South Africa, the United States, there is no equivalent body, and judicial independence is thereby secured through various other mechanisms. Therefore, what is deemed to be an essential measure in some countries may be not considered as such in others. This reveals rather different views on the institutional means needed to protect judicial independence.

The process of defining the institutional requirements of judicial independence has by no means come to an end. For example, the oldest institution of the British constitutional system, the office of Lord Chancellor, has been recently redesigned in an effort to bring about a clearer separation between the branches of the State, and to enhance the independence of the judiciary (see the UK Constitutional Reform Act, 2005; Shetreet and Turenne, 2013).

The protection of judicial independence is usually considered as including various aspects that operate on different levels: external and internal independence, and institutional and individual independence. External independence refers to the independence of the judiciary from the political branches (Executive and Legislative power), as well as any other nonjudicial actor. Although there must, of necessity, be some relations between the judiciary and the political powers (especially the Executive), as stated in the Commentary on the Bangalore Principles "such relations must not interfere with the judiciary's liberty in adjudicating individual disputes and in upholding the law and values of the Constitution" (2007, para. 26). Internal independence focuses on guarantees aimed at protecting individual judges from undue pressure from within the judiciary: from other judges and, above all, from high ranking judges. High ranking judges may, for example, exert supervising power over courts' administration (depending on the organization of the judicial system), but they must not - in any way - influence the substance of judges' decision-making.

Institutional independence pertains to the institutional and legal arrangements designed ex ante by the State to shield judges from undue pressure and influence. From this point of view, the most important factors concern the way in which judges are recruited, evaluated, and disciplined, the governance of the judiciary and courts' administration.

Judicial independence is a complex idea. To ensure judicial independence, many institutional, legal, and operational measures have been put in place.

What trends in judicial independence, United Kingdom?

How judicial independence can be ensured in its essential facets, including individual, institutional, internal, and external independence. A variety of processes are feasible, and a variety of examples are given to promote discussion and foster critical thinking.

As a result, there isn't a perfect approach for adopting judicial independence that works for everyone. In more concrete words, the outcome of a mixture of many requirements, restrictions, and checks and balances, which can differ from one nation to another, is judicial independence.

However, how well these arrangements function will vary depending on the historical, political, legal, and social context in which the judiciary is employed.

Therefore, The preservation of the rule of law and the impartiality of judges depends on independence.
