Medical: Blood Protoplasm Porphyrin is a pigment in the blood protoplasm and other body fluids that is significant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy adults, x is approximately normally distributed with mean and standard deviation . What is the probability that 20 healthy adults will have an average porphyrin level
less than34?
greater than 42?
between34 and 42?
2.) Totals instead of Averages: Airplane Takeoff Time The taxi and takeoff time for commercial jets is a random variablex with a mean of 8.5 minutes and a standard deviation of 2.5 minutes. Assume that the distribution of taxi times is approximately normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after another, and that they take off one at a time on a given runway. What is the probability that for 10 jets on a given runway, total taxi and take off time will be

a.)less than 70 minutes? *Hint: Either multiply and by the sample size nor divideby n.

b.) more than 2 hours?

Confidence Intervals

3.)Profits: Retail Jobs and productivity! How do retail stores rate? One way to answer this question is to examine annual profits per employee. The following data give annual profits per employee (in units of one thousand dollars per employee) for companies in retail sales. Assume thousand dollars.

4.4 6.5 4.2 8.9 8.7 8.1 6.1 6.0 2.6 2.9 8.1 -1.9

11.9 8.2 6.4 4.7 5.5 4.8 3.0 4.3 -6.0 1.5 2.9 4.8

-1.7 9.4 5.5 5.8 4.7 6.2 15.0 4.1 3.7 5.1 4.2
Calculate the mean.
Let us say that the preceding data are representative of the entire sector of retail sales companies. Find an 80% confidence interval for, the average annual profit per employee for retail sales.
Interpretation: Let us say that you are the manager of a retail store with a large number of employees. Suppose the annual profits per employee are less than 3 thousand dollars per employee. Do you think this might be low compared with other retail stores? Explain by referring to the confidence interval you computed in part b.
Hypothesis Testing

4.) Matches: Number per Box A match company sells matchboxes that are supposed to have an average of 40 matches per box, with a standard deviation of 9. A random sample of 94 of the company’s matchboxes gives an average of 43.1 matches per box. Using a 1% level of significance, can you say that the average number of matches in the box is more than 40?

5.) The National Center for Health Statistics reports that the systolic blood pressure for males 35 to 44 years of age has a mean 128 and a standard deviation 15. The medical director of a large company looks at the medical records of 72 executives in this age group and finds that the mean systolic blood pressure in this sample is Is this evidence that the company’s executives have a different mean blood pressure from the general population? Suppose that we know that blood pressures follow a Normal distribution with standard deviation . Use a significance level of .

6.) Medical : Red Blood Cell Volume Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell mean is about ml/kg. Red Blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the results were

32 25 41 35 30 37 29

The sample mean is ml/kg. Let x be a random variable that represents Roger’s red blood cell volume. Assume that x has a normal distribution and . Do the data indicate that Roger’s red blood cell volume is different (either way) from ml/kg? Use a 0.01 level of significance.Responding to an opinion related to sociology: assignment help philadelphia
I’m studying for my Philosophy class and need an explanation.

Response needs to be pertinent and of substance.Must substantiate your responses.

Must be respectfully and worthy of intelectual honesty ,sincerity,and humanity

Responses must be a minimum of 150 words.

Must read this responses and give opinions!!! :

First response:

After watching the video and reading chapter 4, in which according to cultural anthropologists and sociologists, social learning or culture and not biology accounts for differences among people. What this exactly means is that this is called culture that consists of the values, beliefs, systems of language, communication, and practices that people share in common and that can be used to define them as a collective. Establishing that culture also includes the material objects that are common to that group or society showing that among different cultures they can be different but are more equal to their relative context also known as cultural relativism. An example of culture would be many people associate Italy with pizza and pasta. Yet, many Italians eat many other foods, and types of pasta dishes vary throughout Italy.

When someone or myself encounters a culture different from ours, by using cultural relativity we can analyze and understand a culture’s beliefs and practices from that culture’s point of view. What occurs when we use our own culture to understand what we are seeing is called ethnocentrism we are applying our own culture as a frame of reference to judge other cultures, practices, behaviors, beliefs, and people, instead of using the standards of the particular culture involved. For instance, some cultures eat fried crickets instead of thinking, “Fried crickets are disgusting! ” one should instead ask, “Why do some cultures eat fried insects?”.

Being culturally relative lead to overlooking human rights because some cultural tradition that has been done and passed on for several years often violates human rights. As it was shown in the video with female genital cutting. This showed us how it is courteous to go along with other cultural traditions such as rituals; but, female genital cutting violates one’s human rights.

I believe human rights are defined by ourselves as individuals. It is simple for individuals to determine what is wrong or right based off on their morals and beliefs, although, this does not significantly establish that they are right based on the view of their behavior. It is quite difficult to establish if you are discriminating or just unaware of some culture’s practices/traditions. Yet, when a culture’s a practice/tradition puts an individual in danger, I believe this is when it is acceptable to ignore a culture’s practice/tradition and have the person be safe rather than harmed.

Second response:

What it means as to cultural anthropologists and sociologists, social learning or culture, and not biology accounts for different people is how we are raised and the culture our parents have taught us, everyone comes from a different culture. For example, as in the videos, noodles how in America slurping is rude, put in Japan is not. In my culture slurping soup is bad manners, but in other countries is not. It depends on how you take the situation, in my part, I could deal with it, even if it may bother me, but some people may not bother them. Another example is blowing on food, in my culture I do it, but many people think is rude. My mom did it to cool down my food when I was a baby, it depends on your culture. When I encounter a culture different from mine and I cultural relatively to understand by just ignore it or get used to it, cause we all have different ways to deal with the situation. And have to do the best to don’t pay attention, when it deals with friends or co-workers you have to accommodate to the atmosphere. An example of food cultural relativity lead to a different conclusion than ethnocentrism, it can lead to a different understanding by how you wanted to view and just respect their beliefs or deal with ethnocentrism is different since you only believe in your culture is the only one and nothing else matter than your own. Culturally relative lead to overlooking human rights issues, yes because in some countries people don’t have human rights, people have arranged marriage, no free speech, culture really affects human rights. Who defines human rights? human rights are rights you have based on the country you are living in. I know when the behavior is right or wrong by knowing what we did. You know you are being discriminated by how you get treated, and the mood of the place. Being discriminatory by your acts, and how you may be offended the person. I could ignore to protect people if the other person is in danger, or doing something illegally.Statistics exam help RIGHT NOW

Context
A group of 75 college students from a liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The file containing the data is linked below. The purpose of this study (Links to an external site.) was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college have in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.
Variables
The number of alcoholic beverages a student consumes in a week.
Data: Hypothesis test results:
Variable Sample Mean Std. Err. DF T-Stat P-value
number of drinks per week 3.9333333 0.43592434 74 -1.8275343 0.0717
Prompt
The drinks datafile is available in the Data section below.
Let
μ

be the mean number of alcoholic beverages that students in the liberal arts college drink in a typical week. State the hypotheses. Here is a histogram of the data. Can we safely use the t-test with this data? Explain.
Perform the t-test using StatCrunch. (directions)Copy and paste the information from the StatCrunch output window into your initial post. Based on the P-value, state your conclusions in context. Use a 5% level of significance. NOTE: You do not need to double the P-value for this two-tailed test. StatCrunch calculates the P-value for you. Using the context of this scenario, explain the meaning of each of following items from the StatCrunch output for the hypothesis test.
Std. Err (standard error) T-stat (T-score) P-value
EXAMPLE TO ANSWER
1. The hypotheses are:

Ho:
μ

= 4.73

Ha:
μ

≠ 4.73

2. Although the histogram is skewed to the right, we can still do a t-test because n=75 which is more than 30.

3.
One sample T hypothesis test:
μ : Mean of variableH0 : μ = 4.73HA : μ ≠ 4.73

Hypothesis test results:
Variable Sample Mean Std. Err. DF T-Stat P-value
number of drinks per week 3.9333333 0.43592434 74 -1.8275343 0.0717
4. 2(0.0717)= 1.434

1.434>0.05

We do not have enough evidence to reject the null hypothesis that the average amount of alcoholic beverages that students at this college drink is the same as the national average.

5. a) Std. Err. is the standard error, which is an estimate of how far from the actual mean a sample mean is likely to be.

b) T-stat is T-score, which is used in a t-test to find evidence/lack of evidence of a significant difference between population means.

c) The P-value measures the likelihood of getting results as extreme as the sample in a population where the null hypothesis is true.Complete two parts as required.: nursing homework help

Unit Introduction

We are reading taking a short break from our textbook and reading the introduction to the book Post-Racial or Most-Racial by Michael Tesler instead. This reading is posted below. Tesler’s book takes a close look at American sentiments and self-perceptions. When President Barack Obama was elected in 2008, many Americans believed that the first black president surely meant that America has moved past its history of slavery, inequality, and oppression. However, instead the opposite became apparent. Racist and discriminatory attitudes became louder and Obama was more often attacked based on his ethnicity than his actual policies. Tesler discusses these discrepancies using quantitative data and research approaches.

Your film in this unit is about Fred Korematsu, a Japanese American, who fought against the internment of Japanese Americans from 1942-1945. He was charged with a felony for attempting to avoid internment. His case ultimately made its way to the U.S. Supreme Court. In 1983, a federal judge in California overturned his conviction.

Part one

Your reading in this unit discusses whether we live in a “post-racial” or “most-racial” society. Using your sociological imagination discuss whether our society is better described as post or most-racial. Make sure to use sources provided in this course, or if needed other peer-reviewed sources. You can use the Fred Korematsu Story film as an outside source.

Guiding Prompt: “Post-racial” or “most-racial,” is American society past its racial divide? Provide at least two specific examples.

Applied papers: In this applied paper, you are asked to respond to the provided prompt, using the readings and films, and to add some of your own research. Each paper should be about 2 pages long, double-spaced (about 500 words) and address the provided prompt in the following manner:

1. Introduction. What is this unit’s topic about? Respond to the prompt by identifying specific sections in the readings and films that speak to the topic.

2. Research. Identify an artifact or example that highlights the topic in concurrent society. For example, find an article or artifact from at least two places: An American news source, a piece of art (music, written, paint, etc.), an international news source (in English language), or something else relevant that may provide an example or argument that relates to the topic. Some news sources are provided in the course shell in the left-hand menu. However, you may find a different item that would help underscore the issue or your argument.

3. Conclusion. Here, you tie the readings, film, and your found article/item together. What is your take-away in response to the prompt? What are you making of this issue after having done some research?

4. Discussion questions: Provide three (3) discussion questions that you would like your classmates to respond to.

Always cite your sources and provide references at the end of your paper.

Part two

Watch the film The Fred Korematsu Story.Please respond to three of the five following questions in short essay format：

1.Fred Korematsu was surprised by the fact that the government incarcerated both immigrants and first generation Japanese Americans (Americans of Japanese descent born in the U.S. as citizens). Why do you think he made this distinction? What was the basis for the incarceration?

2.If you were subjected to the same forced removal as the Japanese Americans, how might you react? Why? How do you think Japanese Americans reacted? Why?

1）Just go along with things and show your American loyalty?

2）Non-violent, passive resistance?

3）Outwardly fight the forced removal?

3.The U.S. justified the mass incarceration of Japanese Americans because those of Japanese descent were part of an “enemy race.” Was the U.S. at war with a race or a country? Do you see examples of this reoccurring since then?

4.Karen Korematsu said that her father never told her about his famous Supreme Court case. Many incarcerees didn’t mention their imprisonment to their children for years and in some cases, decades. Why do you think this was the case?

5.Why is Korematsu v. United States a landmark civil rights case? Why was it so critical for the legal team to win the 1983 case?
