5. At a school pep rally, a group of sophomore students organized a free raffle for prizes. They claim that they put the names of all of the students in the school in the basket and that they randomly drew 36 names out of this basket. Of the prize winners, 6 were freshmen, 14 were sophomores, 9 were juniors, and 7 were seniors. The results do not seem that random to you. You think it is a little fishy that sophomores organized the raffle and also won the most prizes. Your school is composed of 30% freshmen, 25% sophomores, 25% juniors, and 20% seniors.

a. What are the expected frequencies of winners from each class?

b. Conduct a significance test to determine whether the winners of the prizes were distributed throughout the classes as would be expected based on the percentage of students in each group. Report your Chi Square and p values.

c. What do you conclude about the null hypothesis (the observed and expected data are the same) assuming a 95% confidence?

14. A geologist collects hand-specimen sized pieces of limestone from a particular area. A qualitative assessment of both texture and color is made with the following results. Is there evidence of association between color and texture for these limestones? Explain your answer by testing your null hypothesis assuming a 95% confidence level.

70.  TRUE or FALSE … The standard deviation of the chi-square distribution is twice the mean.

102.  Do men and women select different breakfasts? The breakfasts ordered by randomly selected men and women at a popular breakfast place is shown in the table. Conduct a test for homogeneity at a 5% level of significance (a=0.05).

Suppose an airline claims that its flights are consistently on time with an average delay of at most 15 minutes. It claims that the average delay is so consistent that the variance is no more than 150 minutes. Doubting the consistency part of the claim, a disgruntled traveler calculates the delays for his next

25 flights. The average delay for those 25 flights is 22 minutes with a standard deviation of 15 minutes.

113.  Find df

117.  Let a=0.05.  What is your decision regarding the hypothesis? Write your conclusion in a sentence and discuss whether there is sufficient data to support your decision.  HINT:  See Section 11.6 on “Test of a Single Variance”.

66.  Can a coefficient of determination be negative? Why or why not?

82.  The cost of a leading liquid laundry detergent in different sizes is given in the table.

a. Using “size” as the independent variable (x) and “cost” as the dependent variable (y), and draw a scatter plot using EXCEL.

b. Calculate the least-squares line. Put the equation in the form of: ŷ = a + bx.  See the instructors “EXCEL Tips” for finding a linear regression.

c. Find the correlation coefficient. Is it significant?

d. If the laundry detergent were sold in a 40-ounce size, find the estimated cost.

e. Is the least-squares line valid for predicting what a 300-ounce size of the laundry detergent would you cost? Why or why not?

f. What is the slope of the least-squares (best-fit) line? Interpret the slope.

1. (TCO B) The following is a portion of a qualified audit report issued for a private company.

To the shareholders of Tamarak Corporation,

We have audited the accompanying balance sheet of Tamarak Corporation as of October 31, 2009, and the related statements of income, retained earnings, and cash flows for the past year. These financial statements are the responsibility of the company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

The company has included in property and debt in the accompanying balance sheet certain lease obligations that, in our opinion, should be expensed in order to conform with generally accepted accounting principles. If these lease obligations were capitalized, property would be decreased by $4,000,000, long-term debt by $2,000,000, and retained earnings by $180,000 as of October 31, 2009, and net income and earnings per share would be decreased by $180,000 and $0.62, respectively, for the past year.

Required: Complete the above qualified audit report by preparing the opinion paragraph. Do not date or sign the report.

Instructions:

To understand the validity of an instrument we must critically assess the core concepts that supposedly are being defined, measured and applied in a psychometric test. Having that in mind we have, during the second unit, critically revised the concept of “Intelligence” since the beginnings of “mental tests”, in the late XIX century, until the more recent theories of Intelligence developed in late XX century (specially during the 1980s and 1990s). For that reason the purpose of the this test is to elaborate a single essay that discusses the following:

1. How certain interpretations of the concept of evolution influenced the instrumentation and measurement of “Intelligence” in the “Nature vs. Nurture” debate at the end of the XIX century and the beginning of the XX century.

2. The problems and limitations regarding how “Intelligence” has been measured, defined and applied. 3. How recent theories, specially Robert Sternberg’s and Howard Gardner’s theories, have tried to solve some of these problems and limitations. It is advisable that you take into account the following “guidelines” when elaborating your discussion:

1. Take into consideration the historical overview regarding the theory of evolution and individual differences as discussed in class and on Hergenhahn and Hanley’s (2014) text. It also advisable to look at Sternberg’s (2003) historical revision of some of the theories of Intelligence.

2. Focus on one of the recent theories, either Sternberg’s or Gardner’s, giving examples on how they prove that “Intelligence” cannot be reduced to what usual and traditional psychometric tests measure.

3. Use at least two (2) of the assigned texts. Limit yourself to said texts and the discussion in class. Assigned texts (in the order they were assigned). Hergenhahn, B.R. & Henley, T.B. (2014).

Discussion
Comparison of Health System Characteristics Around the World
How does the U.S. healthcare delivery system compare with other countries’ healthcare delivery systems? What is the relationship of a country’s economic resources to health outcomes? How does the funding of services influence access to care? How does government involvement in healthcare delivery inform the patient/consumer experience?
There are no simple answers to the questions above. Yet, it is essential to engage in thoughtful, ongoing inquiry into questions such as these in order to gain a well-rounded perspective on healthcare delivery. In this Assignment, you will analyze and compare data to deepen your understanding of the U.S. healthcare delivery system, as well as other healthcare delivery systems around the world. Your examination of data can provide valuable insights, but it is also important to consider the context surrounding healthcare expenditures and outcomes. In this Discussion, you will examine health system characteristics, such as government involvement and funding of healthcare delivery in the United States and other nations.
For the Discussion and this week’s Assignment, select one country to compare with the United States in terms of healthcare (i.e., compare the same country in both the Discussion and Assignment).
To prepare for this Discussion:
Review the information related to health system characteristics in the Shi and Singh (2015) course text, as indicated in the Resources.
Research the characteristics of the U.S. healthcare delivery system and the systems of your selected countries using the Walden library and credible websites, such as the Organisation for Economic Co-operation and Development (OECD) site.
Consider the following questions as you research your selected country:
How is the health system organized? Is there a central governing agency?
How does an individual gain access to needed services, including specialized care?
How are healthcare services paid for? For example, does the country have a national health system with tax-funded coverage, a health insurance system with a single payer, a health insurance system with multiple insurers, or something else?
What benefits do people in this country experience because of the health system’s characteristics? For instance, are people guaranteed access to healthcare services? Do patients receive well-coordinated care because their health information is readily available to providers through an integrated technology system? Do they have a great deal of choice when selecting physicians?
What challenges do people in this country encounter? For instance, is there typically a long wait to see a specialist? Do patients encounter adverse effects because medical supplies are not readily available? Are healthcare services prohibitively expensive for most people?
Week 5 Discussion Instructions – 300 -500 words
Describe two or more defining characteristics of the U.S. healthcare system.
Explain how these characteristics compare to the characteristics of the healthcare system of your selected country. (Be sure to identify the country in your posting.)
Explain potential benefits and challenges for people in the United States and your selected country based on the health system characteristics you have identified.
Reminder: Be sure to cite your supporting documentation appropriately in correct APA format.

Week 5 Assignment
International Comparison of Data
The World Health Organization’s “Statistical Information System” is an interactive database that allows you to compare health indicators for multiple countries. For this Assignment, you will compare the country you selected for the Discussion with the United States in terms of healthcare (i.e., please compare the same country in both the Discussion and Assignment.)
To prepare for this Assignment:
Consider the value of using standardized quantitative health measures or indicators to compare information internationally.
Examine the definitions of indicators presented in the Resources, including pages 55–62 of the Shi and Singh (2015) course text.
Use the WHO website to examine country statistics and profiles.
Create a table to record data related to three health indicators for the two countries you are comparing, as illustrated in the example Indicators Chart on this page.
Once your table is complete, compare the data and analyze it in light of the information presented in this week’s Resources and the research you conducted for the Discussion. What insights does this comparison give you about health and disease within the U.S. healthcare delivery system and the system of the other country you selected?
The Assignment
Write a 1- to 2-page paper in which you:
Identify the country that you are comparing with the United States.
Define the three health indicators you have selected for your analysis and explain why you chose them.

Assignment 4.2 Beef Demand Model

A meat packing company hires you to study the demand for beef. The attached data are

supplied. Complete the following tasks, then open the quiz “4.2 Beef Demand” and

complete it.

1. Estimate the demand for beef as a function of the price of beef, the price of pork,

disposable income, and population. Label this as Model 1. Which independent

variables have a significant impact on the demand for beef?

2. The coefficient for the price of beef indicates that a one-dollar increase in price

leads to how large a decrease in quantity demanded?

3. Estimate the demand for beef as a function of the price of beef, the price of pork,

and per capita disposable income (per capita disposable income=[disposable

income/population]; you have to create this variable from the data). Label this as

Model 2. Which independent variables have a significant impact on the demand

for beef?

4. Which Model fits the data better? Comment on why, using statistics from the

regression model.

5. The meat packing company gives you the following assumptions: Price of

beef=$2; price of pork=$2.50; disposable income=$1,000,000; and

population=225. Given this information, use model 1 to complete the following:
