Information from the American Institute of Insurance indicates the mean amount of life insurance per household in the United States is $134,000. This distribution follows the normal distribution with a standard deviation of $30,000.
What is the likelihood of selecting a sample with a mean of at least $137,000? (Round your z value to 2 decimal places and final answer to 4 decimal places.)
d. What is the likelihood of selecting a sample with a mean of more than $126,000? (Round your z value to 2 decimal places and final answer
Find the likelihood of selecting a sample with a mean of more than $126,000 but less than $137,000. (Round your z value to 2 decimal places and final answer to 4 decimal places.)

The U.S. Bureau of Labor Statistics released hourly wage figures for various countries for workers in the manufacturing sector. The hourly wage was $30.67 for Switzerland, $20.20 for Japan, and $23.82 for the U.S. Assume that in all three countries, the standard deviation of hourly labor rates is $4.00.
a. Suppose 44 manufacturing workers are selected randomly from across Switzerland and asked what their hourly wage is. What is the probability that the sample average will be between $30.00 and $31.00?
b. Suppose 36 manufacturing workers are selected randomly from across Japan. What is the probability that the sample average will exceed $21.00?
c. Suppose 50 manufacturing workers are selected randomly from across the United States. What is the probability that the sample average will be less than $22.90?

The purpose of this assignment is to understand the terms import and export, and then explain the advantages or disadvantages of buying imports rather than buying domestic products. You could, for instance, write about an imported automobile, stereo, or household appliance that you bought or considered buying. Include all of the following points in your discussion.

Statistics Homework:
Diabetes and hypertension are two of the most common diseases in Western, industrialized nations. In the United States, approximately 9% of the population has diabetes, while about 30% of adults have high blood pressure. The two diseases frequently occur together: an estimated 6% of the population has both diabetes and hypertension.
1. Are having diabetes and having hypertension disjoint?
2. Draw a Venn diagram summarizing the variables and their associated probabilities.
3. Let A represent the event of having diabetes, and B in the event of having hypertension. Calculate P (A or B).
4. What percent of Americans have neither hypertension nor diabetes?
5. Is the event of someone being hypertensive independent of the event that someone has diabetes?

Neuroinvasive West Nile virus refers to a severe disease that affects a person’s nervous system. It is spread by the Culex species of mosquito. In the United States in 2010 there were 629 reported cases of neuroinvasive West Nile virus out of a total of 1021 reported cases, and there were 486 neuroinvasive reported cases out of a total of 712 cases reported in 2011. Can we conclude that the 2011 proportion of neuroinvasive West Nile virus cases is significantly more than the 2010 proportion of neuroinvasive West Nile virus cases? If you conduct hypothesis testing, you have to consider:
Group of answer choices
a test of two proportions
a test of two independent means
a test of a single mean
a test of a single proportion.

Investopedia defines, “Monetary policy and fiscal policy refer to the two most widely recognized "tools" used to influence a nation's economic activity. Monetary policy is primarily concerned with the management of interest rates and the total supply of money in circulation and is generally carried out by central banks such as the Federal Reserve. Fiscal policy is the collective term for the taxing and spending actions of governments. In the United States, the national fiscal policy is determined by the Executive and Legislative Branches.”
This task will have you explore fiscal policy.

22.1 Negotiable Instrument William H. Bailey, MD, executed a note payable to California Dreamstreet, a joint venture that solicited investments for a cattle breeding operation. Bailey’s promissory note read, “Dr. William H. Bailey hereby promises to pay to the order of California Dreamstreet the sum of $329,800.” Four years later, Dreamstreet negotiated the note to Cooperative Centrale Raiffeisen-Boerenleenbank B.A. (Cooperatieve), a foreign bank. A default occurred, and Cooperatieve filed suit against Bailey to recover on the note.
Is the note executed by Bailey a negotiable instrument? Cooperatieve Centrale Raiffeisen-Boerenleenbank B.A. v. Bailey, 710 F.Supp. 737, 1989 U.S. Dist. Lexis 4488 (United States District Court for the Central District of California)

As health care workers we need to be aware of disease prevalence
and statistics affecting our community and individuals. One of the
functional roles of a Health Information Technician is to be
knowledgeable of the many disease processes, causes, prevention,
and treatment to ensure healthy outcomes. The World Health
Organization (WHO) is an important and factual resource that
provides yearly statistics as well as guidelines to prevent and
decrease the mortality of diseases and their processes.
Access the World Health Organization website and choose a topic
that interests you or one you feel is of great concern in the
United States. Write a discussion post that supports your choice
with ONE pertinent fact, risk factor (s), common symptom(s), and
way(s) of prevention. Your original post must be at least 250

Suppose that we want to test the hypothesis that mothers with low socioeconomic status (SES) deliver babies whose birthweights are different than "normal". To test this hypothesis, a list of birthweights from 69 consecutive, full-term, live-born deliveries from the maternity ward of a hospital in a low-SES area is obtained. The mean birghweight is found to be 116 oz. Suppose that we know from nationwide surveys based on millions of deliveries that the mean birthweight in the United States is 120 oz, with a standard deviation of 23 oz. At α = .06, can it be concluded that the average birthweight from this hospital is different from the national average? (a) Find the value of the test statistic for the above hypothesis. (b) Find the critical value. (c) Find the p-value.
