Industrial wastes and sewage dumped into our rivers and streams absorb oxygen and thereby reduce the amount of dissolved oxygen available for fish and other forms of aquatic life. One state agency requires a minimum of 5 parts per million (ppm) of dissolved oxygen in order for the oxygen content to be sufficient to support aquatic life. A pollution control inspector suspected that a river community was releasing amounts of semitreated sewage into a river. To check his theory, he drew five randomly selected specimens of river water at a location above the town, and another five below. The dissolved oxygen readings (in parts per million) are as follows.

(a) Do the data provide sufficient evidence to indicate that the mean oxygen content below the town is less than the mean oxygen content above? Test using α = 0.05. (Use μ₁ for the population mean for the above town location and μ₂ for the population mean for the below town location.)
State the null and alternative hypotheses.

H₀: (μ₁ − μ₂) = 0 versus H_a: (μ₁ − μ₂) > 0

State the test statistic. (Round your answer to three decimal places.)
t =  

State the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.)

State the conclusion.

H₀ is rejected. There is insufficient evidence to indicate that the mean content of oxygen below town is less than the mean content above town.

H₀ is not rejected. There is sufficient evidence to indicate that the mean content of oxygen below town is less than the mean content above town.    

H₀ is not rejected. There is insufficient evidence to indicate that the mean content of oxygen below town is less than the mean content above town.

H₀ is rejected. There is sufficient evidence to indicate that the mean content of oxygen below town is less than the mean content above town.

(b) Suppose you prefer estimation as a method of inference. Estimate the difference in the mean dissolved oxygen contents (in ppm) for locations above and below the town. Use a 95% confidence interval. (Use μ₁ − μ₂. Round your answers to three decimal places.)
ppm to  ppm

can someone tell me if i am wrong on any of these???? THANKS

In order to be able to deliver an effective persuasive speech, you need to be able to detect fallacies in your own as well as others’ speeches. The following statements of reasoning are all examples of the following fallacies: Hasty generalization, mistaken cause, invalid analogy, red herring, Ad hominem, false dilemma, bandwagon or slippery slope.

1. __________bandwagon fallacy_______ I don’t see any reason to wear a helmet when I ride a bike. Everyone bikes without a helmet.

2. _______red herring__________ It’s ridiculous to worry about protecting America’s national parks against pollution and overuse when innocent people are being endangered by domestic terrorists.

3. _________mistaken cause________ There can be no doubt that the Great Depression was caused by Herbert Hoover. He became presient in 1929, and the stock market crashed just seven months later.

4. _________slippery slope________ If we allow the school board to spend money remodeling the gym, next they will want to build a new school and give all the teachers a huge raise. Taxes will soar so high that businesses will leave and then there will be no jobs for anyone in this town.

5. _______hasty generalization__________ Raising a child is just like having a pet – you need to feed it, play with it, and everything will be fine.

6. ________ad hominen_________ I can’t support Senator Frey’s proposal for campaign finance reform. Afterall, he was kicked out of law school for cheating on an exam.

7. _________________ Our school must either increase tuition or cut back on library services for students.

8. ________hasty generalization_________ One nonsmoker, interviewed at a restaurant, said, “I can get dinner just fine even though people around me are smoking. Another, responding to a CNN survey, said, “I don’t see what all the fuss is about. My wife has smoked for years and it has never bothered me.” We can see, then, that secondhand smoke does not cause a problem for most nonsmokers.

9. _________invalid anaology________ You should raise my grade. I’ve talked to a lot of people in the class, and we all think you grade too hard.

A new school district superintendent preparing to reallocate resources for physically impaired students wanted to know if the schools in the district differed in the distribution of physically impaired. The superintendent tested samples of 20 students from each of the five schools and found 5 physically impaired (and 15 unimpaired) students at School 1, 5 physically impaired (and 15 unimpaired) at School 2, 6 (and 14) at School 3, 4 (and 16) at School 4, and 7 (and 13) at School 5. Using the .05 significance level, test whether the distribution of physically impaired students is different at different schools. Figure the chi-square for this data set yourself (round to two decimal places). What is the chi-square obtained?

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)

A random sample of respondents was drawn from three Latin American countries: Nicaragua, Guatemala, and Costa Rica. The variable if interest is the duration (in months) of stay in the United States during a respondent’s first migration to the United States.

Nicaragua: 4, 6, 6, 6, 12, 36, 36, 36, 36, 60, 72, 78, 96, 120, 126, 156, 162, 162, 186, 540
Guatemala: 1, 1, 12, 24, 24, 24, 36, 36, 42, 60, 78, 84, 102, 102, 102, 102,132, 144
Costa Rica: 12, 12, 12, 12, 14, 15, 15, 18, 18, 24, 36, 48, 66, 120, 150, 150, 174, 282, 288

1. At this point in your efforts, you notice that both Guatemala and Costa Rica have some very low and very high values? Which measure of central tendency is most susceptible to such extreme values?
2. Given your answers to Questions #5 and #7, you are interested in extending the idea that respondents from Latin American countries that are closer to the United States have a higher mean duration of stay than respondents from Latin American countries that are further away. Which country would you expect to have the lowest mean duration of stay during first U.S. migration?
3. Which of the three countries has the lowest mean duration? Does this support your idea that respondents from Latin American countries that are closer to the United States have a higher mean duration of stay than respondents from Latin American countries that are further away?
4. For each country, identify the direction in which (if any) the distribution is skewed? Provide specific evidence using your answers from the previous questions.
5. Select one country from Question #11 and illustrate your conclusion graphically using the histogram. On your graph, be sure to highlight the mode, median, and the mean.
6. Construct box-whisker plot for each country separately. Interpret your findings.
