d. 0.75
e. none of these
2. The distribution of raw scores on a chemistry final is approximately
normal with mean of about 50 and standard deviation of about 10. What
is the probability that a student will have a raw score that is more than
45?
a. 0.7238
b. 0.3085
c. 0.4500

scores.

4. True or False: The standard normal distribution has a mean of 1.
a. True
b. False 5. True or False: The 70th percentile means 70% of the values in the
distribution are above it.
a. True b. False 6. True or False: On a statistics exam, Joe’s score was at the 20th percentile
and John’s score was at the 40th percentile; thus, we can say that John’s
score was twice Joe’s. a. True b. False 7. True or False: On the standard normal curve, the 50th percentile
corresponds to the mean value of the data set. a. True b. False 8. True or False: If a student’s exam score corresponds to a negative zscore, then the student has a score that is less than the mean of the set of
exam scores. a. True b. False 9. If a sample has a mean of 48 and a standard deviation of 3.2, what is the

a. 38.22 b. 42.88c. 53.12d. 46.40e. none of these 10. Find P(-1.2<Z<1.9)
a. 0.9713b. 0.8562c. 0.8020d. 0.7659e. none of these
11. Find c such that P(Z>c)=0.3859
a. -0.29b. 0.35c. -0.35d. 0.29e. none of these
12. If a population has a standard deviation , then the standard
deviation of the mean of 100 randomly selected items from this
population is
a. /100 b.
c. /10 d. 100
e. 1
f. none of these
13. The sampling distribution of a statistic isa. The probability that we
obtain the statistic in repeated random samplesb. The mechanism that
determines whether randomization was effectivec. The distribution of
values taken by a statistic in all possible samples of the same sample size
from the same population d. The extent to which the sample results
differ systematically from the truthe. None of these
14. The expected value of the sampling distribution of the sample mean
is equal to a. the standard deviation of the sampling populationb. the
mean of the sampling populationc. the median of the sampling
population
d. the population size e. none of these

15. Power companies kill trees growing near their lines
to avoid power failures due to falling limbs in storms. Applying a
chemical to slow the
growth of the trees is cheaper than trimming, but the chemical kills some
of the trees. Suppose that one such chemical would kill 15% of
sycamore trees. The power company tests the chemical on 200
sycamores. Consider these a SRS from the population of all sycamore
trees. What is the probability that no more than 32 trees are killed?
a. 0.0571b. 0.6540c. 0.3460d. 0.1598e. none of these

Assignment 2: It May Not Work in Politics

Write a three to four (3-4) page paper in which the student addresses the following three (3) items using headers to separate each response:

1. Congressional Ethics: Identify one (1) member of Congress who has been charged with ethics violations in the past years. Briefly discuss the reason for the charges and provide two (2) reasons why you agree or disagree with the verdict and any penalties. Provide examples to support your answer. Consider how the verdict and penalties impacts your trust of the members of Congress.

2. Third Party Candidates: Discuss two (2) political reasons why a third-party candidate has never been successful in winning a presidential election. Provide examples to support the answer. Consider the political impact of the Republican and Democratic Party if a third party was successful.

3. Federal and State Authority: Identify one (1) current issue facing the United States today (from the past 6 months). Analyze the respective roles of federal and state authorities in addressing the issue. Determine whether the U.S. Constitution constrains the federal and state responses to the issue. Explain.

In your research, you cannot use Wikipedia, online dictionaries, SparkNotes, Cliff notes, or any other Website do that do not qualify as an academic resource.

Your assignment must follow these formatting requirements:

· Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; references must follow APA or school-specific format. Check with your professor for any additional instructions.

· Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required page length.

Important measures in regard to international economics is the balance of payments

/in /by

One of the more important measures in regard to international economics is the balance of payments. Think of it as a national accounting measure that looks at the flow of goods and services into and out of an economy in a given period of time. It also shows capital flows into and out of a country. Until 1980, the United States tended to run a positive-to-neutral balance of payments position and was a creditor nation. In the course of the past 30 years, the United States has moved to a negative balance of payments and to being a debtor nation.

Review and discuss the following:

  • Discuss the importance of the balance of payments as an accounting measure.
  • Discuss the current account and its components and the capital and financial accounts and their components.
  • How important is the U.S. deficit in traded goods in regard to the balance of payments?

How did you get back on track to using the reflective listening skills?

/in /by

Using the reflective listening skills learned in class, students will engage in a challenging conversation with someone outside the class. The conversation should occur with someone you feel diametrically opposed to on a topic, for example, someone who voted differently than you in the election, a friend or acquaintance who disagrees with you on a heated issue, a loved one who feels differently than you on an important matter, etc. While students will determine who to have the conversation with and what the topic is, students should take care to abide by these specific parameters:

The ultimate goal of this assignment is to understand where the other person is coming from. As we recall, reflective listening ultimately boils down to listening to understand.
While at the end of the conversation you may not agree on the topic at hand with the other person, it’s important that you gain an understanding of their perspective through the conversation.
This assignment is not to participate in a “debate” with the other person. It’s not your role to convince them of your point of view — you’re trying to understand where they are coming from and how they came to their values and beliefs.

After you have the conversation, take time to reflect on how the conversation went. How challenging was it to use the reflective listening skills? What worked well for you? What could use improvement in the future? Were there any moments where you almost lost your cool? How did you get back on track to using the reflective listening skills? From your perspective, how did the conversation go overall? How did the other person seem to respond to your use of reflective listening skills? What have you learned from this exercise?
Submissions should be typewritten — word processed — and between 4 to 5 pages double spaced with 12 point font. Papers will not be graded on grammar or spelling, but clarity and attention to these details would be most helpful.
