Asked what the central limit theorem says, a student replies, ¨As you take larger and larger samples from a population, the variability of the sampling distribution of the sample mean decreases.¨ Is the student right? Explain your answer.

Answers

Answer 1

The student is wrong about  central limit theorem.

Central limit theorem (CLT)

Central limit theorem deals with distribution of the mean of sample.the sample means distribution approximates to a normal distribution when the size of the sample becomes larger, regardless of the population's distribution.

Thus, the student is wrong as the CLT does not say anything about given sample's histogram values.

Problem 5: (3 points) What is the purpose of the command interpreter? Why is it usually separate from the kernel? What system calls have to be executed by a command interpreter or shell in order to start a new process?

Answers

The main purpose of a command interpreter is to read commands received from the user or from any command files and execute them through the process of turning these commands into system calls.

As command interpreters are changeable in nature they are not the part of the kernel.

In order to start a new process the system call known as fork and followed by the system call exec must be executed by a command interpreter.

Explanation:

An important part of an operating system that is used for receiving and executing the commands that are received from the user. It is also termed as the shell in some of the operating systems.It is usually separated from the Kernel because it is changeable in nature. It depends on the user who gives commands.

In the Unix operating systems, the system call that must be executed by the command interpreter for the purpose of starting a new process is a fork system call and it must be followed by exec system call for execution. The process that is currently executed will be cloned by a fork system call and exec helps in the execution of the calling process.

What are the basic characteristics of the Creator and his creation according to the Christian worldview?

Answers

Answer:

According to the Christian worldview, God, the creator is mighty and powerful over all things in the universe. He is the judge and provider of things including life and also is the ruler over all his created beings. His creation are supposed to live in his footsteps, for they were made "in his own image".

Explanation:

A Christian worldview is the perspective of an individual or even a group of people based on their beliefs about life and everything from the Bible. This worldview is primarily focused on the viewpoints based off the biblical source.

According to the Christians, the Creator which is God, is the master of all and the source/ beginning and end of all things on earth and the whole universe. They believe that he is the source and solution of life, the giver and taker of life. He is also the judge, savior and also the sustainer of a person's life.

Another belief of the Christians is the oneness of the Father, the Almighty living God and the Son, Jesus Christ. The believers are taught to address God as "Our Father" in the Lord's Prayer. This direct relation of the believers and God is possible through the belief of the Son who was crucified on the cross for the salvation of everyone. So, whoever believes in the death of Jesus for the sins of the world will be able to gain eternal life, is possible through the belief of the Son who acts as the medium/ mediator for the believers to the Father, God.

The belief regarding the created beings is also another focus of the Christian worldview. Biblical sources mandate the beginning of life as being through the creation of man from mud by God, with breath from His own breath, and the woman from the ribs of a man. The beginning of life being from the garden of Eden is also scientifically contrasted by various scientists who believe in the evolution of man from monkeys/ apes.

Explanation:

A researcher wished to determine the effect of fertilizer concentration on plant growth. She put bean seedlings into four groups, with 10 plants in each group. One group was not fertilized. She measured each plant's height weekly for three weeks. How should she plot the data to analyze the effect of fertilizer on plant growth

Answers

The researcher should use the following way to analyze the effect of fertilizer on plant growth:

Plot the plant height on the y-axis and time in weeks on the x-axis. Each fertilizer concentration should be plotted on a separate line.

Explanation:

A graph is a diagram which is used to represent the relation between variable quantities.

Line graphs are commonly used to track changes over short and long periods of time. Line graph provides the result accurately compared to bar graphs, because it can exactly represent the small changes. Line graphs can be used to monitor changes over the same period of time.

To monitor the effect of fertilizer on plant growth, the height of the plant should be plotted on y-axis and time in weeks on the x-axis. The concentration of each fertilizer should be plotted on a separate line.

Final answer:

To analyze the effect of fertilizer on plant growth, a researcher can use either a line graph to plot plant height over time or a bar graph to show average growth after three weeks. It is best to use average growth figures to avoid overcomplication and clearly indicate different fertilizer concentrations and measurement time points.

Explanation:

To analyze the effect of fertilizer on plant growth, the researcher should use a line graph or a bar graph. For a line graph, the x-axis would represent the time in weeks and the y-axis would indicate the average height of the plants. Each line would represent one group of plants treated with a different concentration of fertilizer, including the control group with no fertilizer. A bar graph could show the average increase in height for each fertilizer concentration after three weeks, with one bar for each group.

It's important to make sure that the data is plotted in a way that is easy to interpret. Average growth, fertilizer concentration, and measurement time points should be clearly indicated. Including every single data point might overcomplicate the graph, so focusing on averages could provide a clearer understanding of the fertilizer's impact.

If comparing the effects of different brands of fertilizer, the researcher could use a separate graph or different colored lines or bars within the same graph to represent each brand. Moreover, considering the interaction effects, such as how different amounts of water may influence the effectiveness of each fertilizer, may also be necessary if such a variable is included.

Economic risks relate to difficulties inherent in managing the complex resource flows required by most international firms. True False

Answer: False

Explanation:

''Economic risks relate to difficulties inherent in managing the complex resource flows required by most international firms''.

The statement above is NOT true, that is, it is false. So, let us take one or two things you need to know about ECONOMIC RISKS.

ECONOMIC RISKS: when an investment is exposed to some certain conditions known as the macroeconomic factors/conditions on a foreign land/country which may affect the investment, this exposure is known as economic risks. Such macroeconomic factors include Government or political policies, swings in exchange rates and so on.

TYPES OF ECONOMIC RISK: there are many types of economic risk, I am just going to mention few of them, and they are; Market Prices, Duty Rates, cost of materials, credit risks, minimum wage and so on.

===> Economic risks DOES NOT relate to difficulties inherent in managing the complex resource flows required by most international firms BUT they are risks in which investments in foreign country are exposed to.

Bertold Brecht's alienation effect was designed so that theater audiences could:______.a) avoid being absorbed in the experience and miss the important political point of theater.b) reject ideas of playwrights that might be bad for their character.c) reject silly songs and zany behavior so that they could focus on the important work of theater.d) become absorbed emotionally in the horrors of the play.

Answers

Answer:

a) avoid being absorbed in the experience and miss the important political point of theater.

Explanation:

Bertold Brecht was a German poet and playwright who designed the alienation effect. He wasn't comfortable with the emotional attachment the audience had with characters in a play as a result of emotional manipulation by the film directors.

He politicized "epic drama", a kind of style that seek to allow audience objectivity rather than emotional involvement in a play. He wanted his audience to be objective and hence make rational judgement.

The correct answer is letter A

The alienation of man, for Brecht, does not manifest itself as a product of artistic intuition. Brecht takes care of it consciously and purposefully. But it is not enough to understand and focus on it. The essential thing is not the alienation itself, but the historical effort to de-alienate man.

The role of the dramatic author is not reduced to reproducing, in his work, the society of his time. The main objective, both in terms of content and form, is to exercise a transforming function, which acts revolutionarily on the 'social environment.

You are a university student, but you also wait tables at a restaurant. One evening, one of your professors happens to come in for a meal (awkwardly, on a first date!). Use role theory to describe the interaction (and possible role conflict) that ensues.

Answers

Final answer:

The interaction between the university student and the professor can be described using role theory. Role conflict may arise when the student has to balance their roles as a waiter and a student. To manage this conflict, open communication and finding a balance between the roles is essential.

Explanation:

The interaction between the university student and the professor can be described using role theory. Role theory states that individuals play different roles depending on the situation they are in. In this case, the student plays the role of a waiter at the restaurant and the role of a student at the university. However, when the professor comes into the restaurant, a role conflict may arise as the student has to balance both roles.

The student may feel a sense of tension and dilemma between providing good service as a waiter and maintaining a level of professionalism as a student. This could create an awkward situation for both the student and the professor, especially considering it is the student's first date at the restaurant. The student may struggle to perform both roles effectively, and it may affect their ability to focus on their duties as a waiter or engage in meaningful conversation with the professor.

To manage this role conflict, the student could try to create boundaries and prioritize their roles. They may need to communicate with their professor about their dual role and discuss any limitations or constraints it may impose on their interactions while waiting tables. By open communication and finding a balance between their roles, the student can potentially navigate the situation successfully.
