1. A national newspaper reported that the state with the longest mean life span is Hawaii, where the population mean life span is 77 years. A random sample of 20 obituary notices in the Honolulu Advertizer gave the following information about life span (in years) of Honolulu residents.

(i) Use a calculator with sample mean and standard deviation keys to find x and s. (Round your answers to two decimal places.)

(ii) Assuming that life span in Honolulu is approximately normally distributed, does this information indicate that the population mean life span for Honolulu residents is less than 77 years? Use a 5% level of significance.

(a) What is the level of significance?
  

State the null and alternate hypotheses.

H₀: μ < 77 yr; H₁:  μ = 77 y

rH₀: μ = 77 yr; H₁:  μ > 77 yr    

H₀: μ = 77 yr; H₁:  μ ≠ 77 yr

H₀: μ = 77 yr; H₁:  μ < 77 yr

H₀: μ > 77 yr; H₁:  μ = 77 yr

(b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution.

The Student's t, since we assume that x has a normal distribution and σ is unknown.The Student's t, since we assume that x has a normal distribution and σ is known.     The standard normal, since we assume that x has a normal distribution and σ is known.The standard normal, since we assume that x has a normal distribution and σ is unknown.

What is the value of the sample test statistic? (Round your answer to three decimal places.)
  

(c) Find the P-value. (Round your answer to four decimal places.)

2. The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value of α from the two-tail area row. The critical values are the ±tvalues shown.

Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is μ = 7.4†. A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 36 patients with arthritis took the drug for 3 months. Blood tests showed that x = 8.0 with sample standard deviation s = 1.7. Use a 5% level of significance to test the claim that the drug has changed (either way) the mean pH level of the blood. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to three decimal places.)

State your conclusion ion the context of the application.

Fail to reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level.

Fail to reject the null hypothesis, there is insufficient evidence that the drug has changed the mean pH level.     

Reject the null hypothesis, there is insufficient evidence that the drug has changed the mean pH level.

Reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level.

Compare your conclusion with the conclusion obtained by using the P-value method. Are they the same?

We reject the null hypothesis using the traditional method, but fail to reject using the P-value method.

The conclusions obtained by using both methods are the same.    

We reject the null hypothesis using the P-value method, but fail to reject using the traditional method.

Economist and Nobel Laureate Joseph E. Stiglitz argues that the IMF has failed its mission to secure global economic stability. He identifies the reasons for this failure with changes in the IMF’s mission and economic policies. In his role as Senior Vice President and Chief Economist at the World Bank in the late 1990s, Stiglitz was privy to the policies and failures of the IMF. In his book, Globalization and Its Discontents, Stiglitz lays out an argument for why the IMF has failed in its mission to ensure global economic stability. Stiglitz argues that the IMF’s policies not only do not work, but often make matters worse for the countries in crisis. He highlights several problematic policies:

Capital market liberalization. The IMF pressures countries that petition for IMF loans to open their markets to outside investment capital. Rather than help matters, this approach often makes matters worse as it destabilizes the economy of the country as well as the global economy. Investors may invest huge sums in a country only to pull those investments at a moment’s notice, causing acute economic crises.

Latin America as the template. Stiglitz says that many of the the ideas of the “Washington Consensus” were based on the experience with Latin America. The economic growth in these countries had not been sustained, governments had let budgets run out of control, and loose monetary policy had led to rampant inflation. The belief of the Washington Consensus was that this had happened as a result of excessive government intervention in the economy. So, if government intervention was the problem, then government intervention should be limited. The Washington Consensus pushed for policies such as capital market liberalization. Stiglitz notes that even if this approach was appropriate for some Latin American countries, it did not make sense to apply this policy blindly to other countries in very different situations where this kind of policy might make matters much worse.

Insensitivity to strength of local markets. Stiglitz says that the IMF policy forcing rapid trade liberalization has not only not worked, but does not follow lessons learned from history. He notes the cases of the U.S. and Japan. Both countries had trade protection policies in place until their industries were strong enough to compete in a global market. However, IMF policies forcing trade liberalization on a developing country where industries are not strong enough can actually cause more harm. Local industries could not compete, and rising interest rates made job creation virtually impossible. Says Stiglitz, “Liberalization has, thus, too often, not been followed by the promised growth, but my increased misery.”

Taxation without Representation. Stiglitz notes that even though the IMF is a public institution, funded by money from taxpayers around the world, it is not held accountable to the interests of these taxpayers. He identifies the problem of governance as one of the prime “underlying factors” for problems with the IMF.   (Center on Law & Globalization)

Analyzing the macroeconomic status of a country examines the behaviors within a whole economy. In addition to the macroeconomic factors introduced in the reading materials, other components must be considered when analyzing the economic status of a country. The first component is the misery index, which is the unemployment rate and the inflation rate combined. Another consideration is the economic freedom index, which is an exploration of the overall position of a country in comparison to other countries. Finally, there is the human development index, which focuses on the people within the economy, not just the economic growth within a country. For this assignment, compare the United States and one other selected country of your choice approved by the instructor. Throughout this course, multiple resources have been included in all topic materials to provide websites that will assist in the research required for this assignment. Collect the economic data outlined in the "Country Analysis Matrix," located in Topic Materials and conduct additional research through a minimum of three readings from The Economist. You must provide citations for the three articles from The Economist. In addition to completing the matrix, write a 250-word summary identifying two major economic strengths and two major weaknesses for your selected country. Focus on identifying factors that contribute to the country's overall performance and support the growth of the economy as a whole. For example, has the country grown primarily through export promotion or domestic growth? Finally, point out any significant differences you observe between your selected country and the United States. Use the matrix you have developed and the readings from The Economist to support your analysis. GCU format is required for essays only. Solid academic writing is always expected. For all assignment delivery options, documentation of sources should be presented.

You’re working for the DOJ as an economist in the Economic Analysis Group (EAG) group. You’ve been asked by Nancy Rose, the chief economist at the DOJ and airline-industry expert, to review the American Airlines – US Airways merger. Given the recent consolidation in the airline industry prior to this proposed merger, she along with other regulators are very concerned about the approval of further mergers.

1. American and US Air have claimed that there will be substantial variable costs savings when they merge (as is often the case with proposed mergers).   Suppose in a representative market, there are 4 firms: American, US Air, Southwest, and Delta. Further, suppose that demand is of a constant elasticity form, Q=p^-E.
   1. What is a reasonable value for E based on academic or government research?
   2. Suppose further that the marginal costs for American, US Air and Delta equal $5, and marginal costs for Southwest equal $4, while fixed costs are zero. Take your value you suggest for E above, and calculate the Cournot equilibrium before any merger takes place.   What are the equilibrium quantities and market price?
   3. Suppose the proposed merger is permitted, what happens to equilibrium quantities and the market price? Does this seem like a reasonable prediction? Why or why not?
   4. What would costs need to fall to for the merged entity to do no harm to consumers?

Given your modeling efforts, what would you recommend regarding the unconditional approval of the merger? Are there conditions under which you would let the firms merge? Think big in terms of requests to both airlines and airports that would make you comfortable with the merger being ap

Case Study One:

A patient died after her third cerebral hemorrhage. When the patient was admitted to the hospital following a cerebral hemorrhage, her physician determined that she should be given a specific drug to reduce her blood pressure and make her condition operable, and he directed its administration. For an unexplained reason, the drug was not administered. The patient’s blood pressure rose, and after another hemorrhage the patient died.
