[1] Lipitor is a drug used to control cholesterol. In clinical trials of Lipitor, 94 subjects were treated with Lipitor and 270 subjects were given a placebo. Among those who were treated with Lipitor, 7 developed infections. Among those given a placebo, 27 developed infections. Use a 0.05 significance level to test the claim that the rate of infections was the same for those treated with Lipitor and those given a placebo.[2] Simple random samples of high-interest (5.36%) mortgages and low-interest (3.77%) mortgage were obtained. For the 40 high-interest mortgages, the borrowers had a mean FICO credit score of 594.8 and standard deviation of 12.2. For the 40 low-interest mortgages, the borrowers had a mean FICO credit score of 785.2 and standard deviation of 16.3.a) Use a 0.01 significance level to test the claim that the mean FICO score of borrowers with high-interest mortgage is lower than the mean FICO score of borrowers with low-interest mortgage.b) Does the FICO credit rating score appear to affect mortgage payments? If so, how?
The test of interest here is,
As here the sample size for both the samples are large enough so we can assume the normality using CLT and thus a Z-test would be appropriate. And the hypotheses also show that it’s a left tail test.The output is given below,
Here the lower p-value suggests that we should reject the null hypothesis and conclude that the mean FICO score of borrowers with high-interest mortgage is lower than the mean FICO score of borrowers with low-interest mortgage.
Note that the above analysis showed that the interest rate is higher for the group with lower FICO scores. Thus the FICO credit rating scores appear to affect mortgage payments. If the FICO score is high then the interest rate is expected to be low so the mortgage payments would be low. And for low FICO score the opposite is expected to be observed.[3] A random sample of the birth weights of 186 babies has a mean of 3103g and a standard deviation of 696g (based on data from “Cognitive Outcomes of Preschool Children with Prenatal Cocaine Exposure,” by Singer et al., Journal of the American Medical Association, Vol. 291, No. 20). These babies were born to mothers who did not use cocaine during their pregnancies. Further, a random sample of the birth weights of 190 babies born to mothers who used cocaine during their pregnancies has a mean of 2700g and a standard deviation of 645g.a) The birth weights of babies are known normally distributed. Use a 0.05 significance level to test the claim that both samples are from populations having the same standard deviation.b) Using your finding in (a), construct a 95% confidence interval estimate of the difference between the mean birth weight of a baby born to mothers who did not use cocaine and that of a baby born to mothers who used cocaine during their pregnancies.c) Using your finding in (b), does cocaine use appear to affect the birth weight of a baby? Substantiate you conclusion.
a) Here we need to test for the equality of the standard deviation (same as variance) so the hypotheses of interest are,
As this is two sample test for standard deviation or variance so the test can be performed using a F test. The obtained output is given below.-value is larger than the significance level so we are failing to reject the null hypothesis and concluding that the data does not suggest that both samples are from populations having different standard deviation.b) Here we found out that the variations are not different in two groups so we should use a pooled variance t-test.
From the values from above table,95% confidence interval for difference =
c) From the above calculated confidence interval we can see that the confidence interval does not contain the value 0. So based on the findings we can conclude that cocaine use appears to affect the birth weight of a baby.[4] A large discount chain compares the performance if its credit managers in Ohio and Illinois by comparing the mean dollars amounts owed by customers with delinquent charge accounts in these two states. Here a small mean dollar amount owed is desirable because it indicates that bad credit risks are not being extended large amounts of credit. Two independent, random samples of delinquent accounts are selected from the populations of delinquent accounts in Ohio and Illinois, respectively. The first sample, which consists of 15 randomly selected delinquent accounts in Ohio, givens a mean dollar amount of $524 with a standard deviation of $38. The second sample, which consists of 20 randomly selected delinquent accounts in Illinois, gives a mean dollar amount of $473 with a standard deviation of $22.a) Assuming that the normality assumption, test to determine if the population variances are equal with ? =0.05.Here we need to test for the equality of the variance so the hypotheses of interest are,
As this is two sample test for variance and normality assumption is valid so the test can be performed using a F test. The obtained output is given below.F Test for Differences in Two Variances

b) Test with ? =0.05whether there is a difference between the population mean dollar amounts owed by consumers with delinquent charge accounts in Ohio and Illinois.Here the population variances are not equal so we should run a separate variance t test. The results are as follows,Separate-Variances t Test for the Difference Between Two Means(assumes unequal population variances)DataHypothesized Difference0Level of Significance0.05Population 1 Sample Sample Size15Sample Mean524Sample Standard Deviation38.0000Population 2 Sample Sample Size20Sample Mean473Sample Standard Deviation22.0000

Here based on the result we are rejecting the null hypothesis and thus the conclusion is based in the data there is a difference between the population mean dollar amounts owed by consumers with delinquent charge accounts in Ohio and Illinois at 0.05 significance level.
c) Assuming that the normality assumption and the condition you checked in a) hold, calculate a 95 percent confidence interval for the difference between the mean dollar amounts owed in Ohio and Illinois. Based on this interval, do you think that these mean dollar amounts differ in a practically important way?
Here the 95% confidence interval is =
As we can see the computed confidence interval has values not so high as lowest is 28.10 so based on this interval, I don’t think that these mean dollar amounts differ in a practically important way.

History of americas quiz 3

Question 1
The Monroe Doctrine stipulates:
  America for the Americans, no further European intervention unless is done in existing European colonies in the Americas.
  A part of US Foreign policy under the Good Neighbor policy. 
  Teddy Roosevelt’s idea of American Imperialism 
  Commercial trade doctrine between the United States, Great Britain, and Latin America.
Question 2
The Corollary to the Monroe Doctrine, or Roosevelt’s Corollary, represents an expansion of the Monroe Doctrine.  The corollary stated:
  “…that not only were the nations of the Western Hemisphere not open to colonization by European powers, but that the United States had the responsibility to preserve order and protect life and property in those countries, and thus justifying US intervention in the region.”
  “…it represents an addendum to the Monroe Doctrine added in 1905.” 
  “…favors European intervention in the Western Hemisphere.” 
  “…nations in the Western Hemisphere are to engage in trade exclusively with the United States.”
Question 3
The Dirty War was a period of state sponsored terrorism present in the 1970s in Latin America.  This state terrorism had one objective in mind:
  The eradication of political dissidence. 
  A general support to leftist movements by authorities. 
  Incorporate urban and rural leftist guerrilla movements to mainstream society.
  Provide military training to dissident groups. 
Question 4
During the Progressive Era, working woman – immigrant and native, working class and professional – became a symbol of female emancipation. In her influential book Women and Economics, Charlotte Perkins Gilman wrote that a growing number of younger women desired a lifelong career. What was Perkins Gillman’s main argument?
  Women were fulfilled with their assigned role of “house service.” 
  Women experienced not fulfillment but oppression, and the housewife was an unproductive parasite, little more than a servant to her husband and children.
  Women were satisfied with the prevailing gender norms. 
  The prevailing gender norms made women capable of contributing to society and enjoy freedom.
Question 5
According to lecture, one of the reasons that led to the Revolution in Mexico in 1910 was:
  The inclusion of the Mexican middle class in the political process. 
  Concessions made by the Porfirian elite to the middle class in Mexico. 
  An alliance forged between the middle class and the Mexican elite. 
  Politics of exclusion. 
Question 6
Formed in 1905, the Industrial Workers of the World (IWW) sought to mobilize the immigrant factory labor force, migrant timber and agricultural workers, women, blacks, and even the despised Chinese. In addition to organizing labor in an intersectional fashion, what other factor attracted the attention to the IWW?
  Their battle for freedom of speech. 
  Their songs denouncing unfair labor practices. 
  Their alliance with big business. 
  Their support of skilled industrial and craft laborers, nearly all of them white.
Question 7
During the Progressive Era, Carlos Montezuma became an outspoken critic of federal Indian policy. What is Montezuma’s main argument in his article “What Indians Must Do,” published in the Society of American Indians?
  Montezuma condemned federal paternalism toward the Indians and called for the abolition of the Bureau of Indian Affairs.
  Montezuma’s writing had a tremendous influence at the time on government policy.
  Montezuma praised federal paternalism toward Indians. 
  Montezuma supported the transformation of communal landholdings on reservations into family farms.
Question 8
Throughout the 20th century, every single Latin American nation was ruled by a military regime, with the exception of one country:
  Costa Rica 
  Colombia 
  Mexico 
  Chile 
Question 9
By the 1950s, much of the promise of development and democracy seemed hollow. If reform was not successful in addressing Latin America’s problems, what option was followed by five nations?
  Continue to rely on US economic and political dependency. 
  Populism. 
  Military regimes. 
  Revolutionary Option 
Question 10
What are the four stages of social movements?
  Emergence, coalescence, bureaucratization, decline. 
  Repression co-option, success, failure. 
  Clandestinely, underground, implicit, mainstream. 
  Development, diversification, stagnation, boom. 
Question 11
In the study of people across time, professionals often times employ a periodic approach over a thematic approach. In studying history by periods, we get a false sense of terminality. The alternative to this false sense of terminality is the thematic approach of changes and continuities. What is the advantage of studying history through the theme of changes and continuities?
  The theme of changes and continuities makes history easier to understand, since time is treated in a linear fashion, not in a circular manner.
  By studying history in a thematic approach, we get a better sense of how people fare across time and get a better sense of what conditions have really changed, or if exploitative conditions continue to be the same as in the past.
  Thematic approach gives historians a better understanding on how to prevent making the same mistakes from the past.
  Thematic approach allows historians to better predict the future. 
Question 12
Founded in 1969, the Weather Underground Organization operated in a clandestine fashion for almost 11 years.  What was the goal of this organization?
  The violent overthrow of the US government and the substitution of the capitalist system with a more humane one.
  Work with representatives of the US government to reform the capitalist system.
  Change the US system through a reformist agenda. 
  A state sponsored leftist organization to overthrow the US government. 
Question 13
The Weather Underground, initially the Weatherman and eventually the Weather Underground Organization (WUO), took its name from a popular Bob Dylan song and grew out of Students for a Democratic Society (SDS), the biggest and most organized representation of radical white youth of the 1960s. Inspired by the Civil Rights Movement, Black Power Movements, and counting as their heroes the Black Panther Party for Self Defense, the WOU say one action as a way to express its solidarity with the Third World, within and outside the United States, and that action is:
  Vietnam War. 
  Peace Movement. 
  Clandestine operations/operating underground.

  Guerrilla Warfare. 
  The Communist Manifesto. 
  Prairie Fire. 
  Das Kapital. 
Question 15
The term “feminism” entered the political vocabulary for the first time in the years before World War I.

Who was responsible for placing the issue of birth control at the heart of the new feminism?
  Margaret Thatcher. 
  Simone de Beauvoir. 
  Margaret Sanger. 
  Gloria Steinem.

  The need to create a more homogeneous national culture. 
  The concept of the melting pot was used to quickly assimilate and Americanize as many recently arrived immigrants.
  A monolingual approach (English only) was used to accomplish assimilation.
  All of the above 
Question 19
Dorothy Counts and Ruby Bridges are best remembered for being the first individuals to carry out the basic tenet of the landmark Supreme Court decision, Brown v. Board of Education.
  Integration. 
  Segregation. 
  Separate but equal doctrine. 
  Equal protection test. 
Question 20
The Harlem Hellfighters and the Tuskegee Red-Tail Angels are two prime examples of not only the contradictions of being an American, but also of blatant racial segregation. Regarded as one of the worst decisions in U. S. Supreme Court history, it established the separate but equal doctrine.

Mechanisms of accountability | Law homework help

Mechanisms of Accountability
Note: In Week 5, the Application Assignment is to be completed before the Discussion question.
Congress, the president, and the courts have developed mechanisms of accountability used in the oversight of rulemaking. Congress and the president have a vested interest in the oversight of rulemaking because they want to ensure that statutes are carried out the way they intended. Courts, on the other hand, engage in the oversight in rulemaking to ensure that the rules the agency creates and enforces are constitutional. Given that each branch performs oversight differently by using different mechanisms of accountability, the question of which branch, and more specifically, which mechanism, is most effective arises. In this assignment, you become familiar with the mechanisms of accountability and reflect on which are most effective in the oversight of rulemaking.
To prepare for this assignment:

Review Chapter 6 in Rulemaking: How Government Agencies Write Law and Make Policy. Pay attention to the mechanisms of accountability used by the three branches of government in the oversight of rulemaking.
Select one mechanism used by each branch of the government in the oversight of rulemaking.
Consider the similarities and differences between and among the mechanisms you selected.
Select two mechanisms from the readings that you think are most effective in the oversight of rulemaking and consider why.

The assignment (1–2 pages):

Compare (similarities and differences) the mechanisms of accountability you selected.
Briefly describe the two mechanisms you think are most effective in the oversight of rulemaking and explain why. Be specific.
Explain at least one insight you had or conclusion you drew about the mechanisms of accountability as a result of completing this assignment.

Support your Application Assignment with specific references to all resources used in its preparation. You are asked to provide a reference list only for those resources not included in the Learning Resources for this course.
