Major health studies try very hard to select a sample that is representative of the various ethnic groups making up the U.S. population. Here is the breakdown, by ethnicity, of subjects enrolled in a major study of sleep apnea: White- 4821 Hispanic-277 African American- 510 Asian/Pacific- 88 Native American- 598 Total- 6294 The known ethnic distribution in the United States, according to census data, is as follows: White-0.756 Hispanic- 0.091 African American- 0.108 Asian/Pacific- 0.038 Native American-0.007 Total-1
We want to know if the data from the sleep apnea study support the claim that the ethnicity of the subjects fits the ethnic composition of the U.S. population. What does the null hypothesis for this test state? a. All five counts are equal. b. All five sample proportions are equal. c. All five population proportions are equal. d. All five population proportions are equal to their respective U.S. census proportions.
What is the expected count of Hispanics under the null hypothesis (show calculation)? a. 277 b. 25.207 c. 572.754 d. 152.72 software gives a chi-square statistic χ2 = 7256.21 for these data. What is the P-value for this test? a. Greater than 0.05 b. Less than 0.05 but greater than 0.01 c. Less than 0.01 but greater than 0.001 d. Less than 0.001
at significance level alpha = 1%, what should you conclude? a. composition of the U.S. population. b. The data are consistent with a uniform distribution of ethnicities. c. The data prove that the population studied matches the ethnic composition of the U.S. population. d. We are unable to conclude anything because the test assumptions are not met.

In 2015, the average cost of attendance at public 2-year colleges and technical schools across the United States was $12,260. A researcher wants to know if the 2-year colleges in Michigan are less expensive.
1. A QQ-plot of the cost of attendance at public 2-year colleges and technical schools is shown below. Based on this plot, is it reasonable to use this data to evaluate the research question? Why or why not?
? Yes No because ? The population data
distribution seems approximately normal. The population data
distribution does not seem approximately normal. A sample size of
15 is too small. A sample size of 15 is very
large.
The researcher decides to conduct a hypothesis test. They take a
random sample of 15 such schools in Michigan and find a sample
average of 10173 with a standard deviation of 1536. Conduct a
hypothesis test to determine if the average cost of attendance at
2-year colleges in Michigan is lower than the national average.
Round all numeric results to 4 decimal places.
2. Which set of hypotheses should the researcher use?
A. ?0H0: ?μ = 12,260 vs. ??HA: ?≠μ≠ 12,260
B. ?0H0: ?μ = 12,260 vs. ??HA: ?μ <
12,260
C. ?0H0: ?μ = 12,260 vs. ??HA: ?μ > 12,260
3. Calculate the test statistic.
4. Calculate the p-value.
5. Based on the p-value, we have:
A. little evidence
B. some evidence
C. strong evidence
D. very strong evidence
E. extremely strong evidence

Analyze the health status of a specific minority group. Select a minority group that is represented in the United States (examples include American Indian/Alaskan Native, Asian American, Black or African American, Hispanic or Latino, Native Hawaiian, or Pacific Islander).
In an essay of 750-1,000 words, compare and contrast the health status of the minority group you have selected to the national average. Consider the cultural, socioeconomic, and sociopolitical barriers to health. How do race, ethnicity, socioeconomic status, and education influence health for the minority group you have selected? Address the following in your essay:
What is the current health status of this minority group?
How is health promotion defined by this group?
What health disparities exist for this group?
Describe at least one approach using the three levels of health promotion prevention (primary, secondary, and tertiary) that is likely to be the most effective given the unique needs of the minority group you have selected. Provide an explanation of why it might be the most effective choice.
Cite a minimum of three references in the paper.
You will find important health information regarding minority groups by exploring the following Centers for Disease Control and Prevention (CDC) links:

What are health disparities? What are health inequalities? What is the difference if any? What social determinants were you aware of before doing this reading and which were new to your way of thinking about obesity? How will knowledge of these Social Determinants of Health change your future practice as a health professional? There are many perceptions about obesity that exist in society. One is that obesity stems from people making unhealthy choices and that if we just educate people about how to eat healthy and how to be active regularly this will solve the problem. Discuss, relative to the social determinants of health. When thinking about obesity prevention many people gravitate towards nutrition and physical activity education at the individual level of the SEM. We learned last week that interventions at the individual level of the SEM are expensive and often less effective than initiatives that target changes the higher levels of the SEM. If you could wave your magic wand, what three things would you change to close the socioeconomic and racial obesity gaps in the United States? In the article "Taking Action on the Social Determinants of Health in Clinical Practice: A Framework for Healthcare Professionals", the authors say "Training physicians, nurses and other allied health workers to address the social determinants of health is considered one of the key principles for promoting more equitable health outcomes for patients, families and communities. The article suggests that at the patient level, health professionals should "ask patients about social challenges in a sensitive and caring way". Please discuss if this is common protocol in your profession, if yes - give context (how, where, when, what) it is done, and if no - share why and in what practical situations you think it would be helpful if any.

THE RESILIENTARMOUR Corporation is an American company that manufactures cost-effective protective covers for automobiles made out of innovative composite material, which currently are being sold only in the United States. ResilientArmour currently produces and sells 100,000 protective covers a month and operates its one factory at 60 percent capacity. At that output, the average total cost (ATC) of manufacturing a protective cover is $19.00. Experience has shown that the ATC decreases as output is expanded beyond 100,000 units per month but rises again if output is increased above 125,000 units per month.
THE RESILIENTARMOUR Corporation normally sells its protective covers domestically for $24.00 each. It recently received an order for an additional 10,000 protective covers per month from a buyer in a foreign country where THE RESILIENTARMOUR Corporation would like to do business. This buyer specified that it would pay no more than $14.00 per protective cover. The firm’s accountants estimate that at 110,000 units a month, the ATC of producing a protective cover would be $18.00. THE RESILIENTARMOUR executives want to accept the order.
Draw the firm’s ATC curve and fit the MC curve to it. Then estimate MC at Q = 110,000. Use the profit-maximizing rules (assume P = MR for this paper) to answer the following questions:
Should THE RESILIENTARMOUR Corporation accept the offer?
If they accept the offer, will their profit rise or fall? By how much?
Are the accountants correct in their analysis? What would the production manager say?
Could the firm fill this order in their existing plant? Or, must expansion take place?
What changes in workforce, staffing, and procuring raw materials might be required to fulfill this order?
Whether this order is profitable or not, would it make sense to accept the order in order to expand into an international market?
