Suppose Jamal is studying poverty in his economics class, and he wants to compare the proportion of individuals living below the poverty line in the western United States in different years. He collects data on a simple random sample of people from 2013 and a simple random sample of people from 2014. His data are summarized in the table.
| Population | Population description |
Sample size |
Number of successes |
Proportion of sucesses |
|---|---|---|---|---|
| 1 | population in 2013 | n1=486 | X1=74 | ^p1=0.15226 |
| 2 | population in 2014 | n2=490 | X2=69 | ^p2=0.14082 |
Jamal wants to run a two-sample z‑test for the difference of two proportions to test the alternative hypothesis, H1:p1>p2, against the null hypothesis, H0:p1=p2, where p1 is the proportion of population in 2013 that are living below the poverty line, and p2 is the proportion of population in 2014 that are living below the poverty line. Jamal selects a significance level of α=0.10.
Compute the z‑statistic and P-value for Jamal’s z‑test for the difference of two proportions, p1−p2. Give your answers precise to three decimal places.
Based on your answers and a significance level of α=0.10, complete the following sentences to state the decision and conclusion of Jamal’s test.

Part II: A Case Study in Chapter 13 Bankruptcy - Chapter 13: What Debts Are Dischargeable? In re Ryan - Read the case study below concerning Chapter 13 bankruptcy and answer the three questions at the end of the case study. Be certain to clearly identify your answers to all three questions and be complete in your responses. 389 B.R. 710 9th Cir. BAP, (Idaho, 2008) On July 13, 1995, Ryan was convicted of possession of an unregistered firearm under 26 U.S.C. §5861(d) in the United States District Court for the District of Alaska. Ryan was sentenced to fifty-seven months in prison followed by three years of supervised release. In addition, Ryan was ordered to pay a fine of $7,500…, costs of prosecution in the amount of $83,420, and a special assessment of $50.00. Ryan served his sentence. He also paid the $7,500 fine. The district court, following an appellate mandate, ultimately eliminated the restitution obligation. On April 25, 2003, Ryan filed a petition for bankruptcy relief under chapter 7 in the District of Idaho. He received his chapter 7 discharge on August 11, 2003. Shortly thereafter, Ryan filed a case under chapter 13, listing as his only obligation the amount of unpaid costs of prosecution owed to the United States (“Government”).… Ryan completed payments under the plan, and an “Order of Discharge” was entered on October 5, 2006. The chapter 13 trustee’s final report reflected that the Government received $2,774.89 from payments made by Ryan under his plan, but a balance of $77,088.34 on the Government’s costs of prosecution claim remained unpaid. Ryan then renewed his request for determination of dischargeability. The bankruptcy court held that the unpaid portion of the Government’s claim for costs of prosecution was excepted from discharge by § 1328(a)(3). Ryan appealed. The Court concluded that the exception to the discharge included in [Chapter 13] for “restitution, or a criminal fine, included in a sentence on the debtor’s conviction of a crime” does not cover costs of prosecution included in such a sentence, and REVERSED the bankruptcy court’s judgment.
Case Questions 3. Why did the court decide that Ryan’s obligation to pay “costs of prosecution” was not precluded by the limits on Chapter 13 bankruptcies imposed by Congress?

Is the number of tornadoes increasing? In the last homework, data on the number of tornadoes in the United States between 1953 and 2014 were analyzed to see if there was a linear trend over time. Some argue that it’s not the number of tornadoes increasing over time, but rather the probability of sighting them because there are more people living in the United States. Let’s investigate this by including the U.S. census count (in thousands) as an additional explanatory variable (data in EX11-24TWISTER.csv).
Fit one SLR model with year as the predictor, another SLR model with census count as the predictor. Write down the two models. Are year and census count significant, respectively?

Please write a short response to each of the paragraphs below:
1.
Define eurodollar and eurocurrency.
Eurocurrency is defined as any currency that is deposited into a different country’s bank. For example, if someone were to deposit Canadian currency into a U.S. bank, that currency would be considered eurocurrency. Eurocurrency is highly used for international trade and to apply for international loans. Eurocurrency is largely used by the wealthy and large corporations as a way to avoid regulations, tax laws, and high interest rates.
“The term eurodollar refers to U.S. dollar-denominated deposits at foreign banks or foreign branches of American banks (“Eurodollar” 2018).” The advantage to the eurodollar is being able to avoid regulations of the Federal Reserve. The disadvantage is the high interest these deposits could incur due to having no regulations. Banking outside of the country offers a potential for higher profits due to the banks being unregulated; however, the instability of these offshore banks is at a higher risk.
2.
What is the Glass-Steagall Act? Where and when was it enacted? What are its 3 provisions? When was it repealed?
The Glass-Steagall Act (also known as the Banking Reform Act of 1933) was responsible for separating commercial and investment banking activities. This was enacted in the United States in 1932 during the Great Depression. The Glass-Steagall Act created the Federal Deposit Insurance Corporation (FDIC) and enforced bank reforms, provided stability and reduced risks in the banking industry, and prohibited bank-holding companies from owning other financial companies. Basically, commercial banks were only allowed to take deposits and make loans and investment banks were only allowed to underwrite and deal with securities. The Glass-Steagall Act was repealed in 1999 by President Clinton. Many people believe that the repeal of the Glass-Steagall Act lead to the 2008 financial crisis in the United States.
3.
Indirect finance- Is where borrowers borrow funds from the financial market through indirect means, such as through a financial intermediary. This is different from direct financing where there is a direct connection to the financial markets as indicated by the borrower issuing securities directly on the market.
Debt- Something, typically money, that is owed or due. (The state of owing money)
Equity- A stock or any other security representing an ownership interest. (The value of the shares issued by the company)

In 1977, Honda, a Japanese company, announced plans to build a motorcycle manufacturing plant in the United States near Marysville, Ohio, and in 1980 announced plans to build an automobile manufacturing facility in the same area. Ever since the company made these announcements, Honda’s history has been nothing but impressive.To empha- size this success, the Marysville Auto Plant now produces the Accord Coupe for export to Japan. Honda of America has become a leading auto exporter in the United States, and the motorcycle plant has produced its one-millionth unit of the Gold Wing motorcycle. Many maintain that the following belief statement, which appears prominently on the Honda of America website, is a primary reason for the company’s success: “Why do people want to work for Honda? How does Honda achieve industry-leading quality year after year, mak- ing extremely complex products such as cars, trucks, motor- cycles, and engines? The answer is in Honda’s foundation
principle—the tenant upon which all the other Honda phi- losophies are based. It’s called Respect for the Individual.”
Founders Soichiro Honda andTakeo Fujisawa believed in creating a workforce in which each member’s ideas received the full consideration and respect of the group. People are diverse and that’s a good thing, Mr. Honda believed, because diversity of thought, skills, background, and experiences can enrich the workplace and the product, if the differences are allowed to generate ideas.
In order for the associates’ best ideas to come forward, they must feel valued and comfortable speaking up and in- teracting with their work groups.That’s where respect comes in. Only in an atmosphere of maximized respect and inclu- sion can a workforce reach its highest levels of achievement.
Activities
You have just been contacted to interview for the top management position at Honda of America. You would be responsible for both automobile and motorcycle manufac- turing. Before you visit the Marysville facility for a series of face-to-face interviews, however, you have been asked to answer the following questions related to your own beliefs about how managers should handle people. Answer the fol- lowing questions in preparation for your trip to Marysville.
What is your personal philosophy about using “job design” as a tool for motivating Honda of America employees?

Use a general supply and demand model to explain the following: Several hotel-resorts have opened in the past decade in Las Vegas. The Bellagio has world-class art and the Paris LV is a recreation of Paris (without the rude French people). These and other new hotels have increased the supply of rooms in Las Vegas by 25%, however, room rates have doubled over the same time. How is this possible?
In: Economics
A 300-room hotel in Las Vegas is filled to capacity every night at $80 a room. For each $1 increase in rent, 3 fewer rooms are rented.
At what rate should the rooms be rented to produce the maximum revenue and how many rooms are rented at that rate? What is the maximum revenue? Write your results in a sentence as what each number means and represents. Please include all steps needed
