ROI Department

A release of information (ROI) department or division is found in virtually every hospital. HIPAA and State guidelines strongly direct the rules and regulations of patient information. ROI departments perform such tasks as obtaining patient consent, certifying medical records, and deciding what information can be released. The ROI department is often found within the health information management department of a hospital.

In your own words, construct a 2-3 page APA-formatted synopsis of the main points of this information. Remember to cite your resources.

Suppose you want to know if there is any association between soda consumption and obesity in children.

1. Think about how you would go about organizing such a statistical study. What steps would you have to take/what items would you need to include in order to get it off the ground?

2. In your statistical study what is the:

• Population?

• Parameter?

• Sample?    

• Sample Statistics?

3. Given the 4 sampling methods that we have discussed, which one makes the most sense in your study?

4. Why did you choose this method?

2. Let’s say that polls show that 53% of voters plan to vote for Candidate A in the upcoming election with a margin of error of 4%. Can you safely predict that Candidate A will win the election? Explain your answer.

3. Should you trust that you will get a good deal in a store if you see a sign outside the store saying “EVERYTHING IN THE STORE IS up to 80%OFF” Support your conclusion with reasoning.

4. Explain why ‘Are you in favor of a less expensive cell phone plan?’ is a misleading poll question.

5. What crucial information is missing from the following news statement that might make you view the results differently: A poll reveals that 77% of Americans support affirmative action.

6. In 2013 a soda company purchased an seltzer company and later did a study on how seltzer was a much healthier alternative to soda and encouraged people who want to lose weight to start drinking seltzer.

1. What type of study would have taken place, observational or experimental? Explain your answer.

2. Would a blind study be needed? If so would it need a double blind or single blind? Explain your answer.

3. How many groups would possibly be needed to do the study and what would they be considered, controlled or treated?

4. Should you trust this experiment and why?

Use supply-demand diagrams to illustrate the
situation in which demand increases and supply decreases at the same
time. Indicate what the model predicts regarding the price change and
quantity to equilibrium. Carefully label your diagram and
explain it. Discuss and explain completely.

Analyze new monetary policy actions undertaken by the U.S. government from 2000 - 2010 by describing their intended effects, using macroeconomic principles to explain the actions.

•You should specifically state what the intent of the actions were - for instance, the Fed may have used expansionary policy to help expand the economy in response to a recession. Such policies could have been buying up government bonds - this puts money into the economy since the Fed is buying these bonds from a bank and then the bank can use that money in the economy. This open-market operation increases the money supply.

Then, use our macroeconomic principles and models (like the Supply and Demand of Money model, AD-AS model to show the impact of interest rates on equilibrium GDP, Phillips Curve, etc.) to explain why the action would lead to the outcome desired by the government.

please relate the answer to 2000-2010 and please add a reference, thank you so much!

Question 1: forces of supply and demand determine the prices which prevail for most goods and services. Take a look again at any Supply/Demand chart. What or who is represented by the segment on the demand curve which is located below the equilibrium price? In truth, this segment represents those would like to buy the particular good if the price was lower, but can’t (or choose not to) buy the good at its currently higher price. Perhaps this is trivial for goods like lattes or services like travel to the Bahamas (it’s not a tragedy that some cannot afford a latte or a trip to Bahamas, right?), but think about other goods, such as antibiotics, or services such as education. If the market sets the price, then there will always be some who can’t quite pay the price required. Does this feature of the market system strike you as immoral? Because “the market” (forces of supply and demand) does not guarantee that everyone who needs antibiotics will get them, should the market be abandoned in favor of some other system of pricing and distributing goods and services? Why or why not? (Consider this from a Christian perspective as well, if you like.)

Question two: Think about the law of supply. It states that as prices rise, quantity supplied will rise, and as prices fall, quantity supplied will fall. Now think about the flat-screen TV market. Over the last 15 years or so, the prices have come down significantly, but there are many more flat-screen TVs produced (supplied) today than there were 15 years ago. Does this violate the law of supply? Why or why not?

Please explain in detail and give examples

1. Open the Corn Yield dataset. There you see data recorded from an experiment to test 4 organic pesticide methods (wasps, nematodes, pepper spray, and bacteria) to see if they eradicate corn weevils better than a standard chemical pesticide (control). For each method, effectiveness is determined by the average weight in grams of corn that is yielded from a randomly selected ear of corn.

1. Use Minitab to do an Anderson-Darling test on the Yields to determine if the normality assumption for a valid ANOVA can be considered to be met. What is your conclusion?
2. Use Minitab to compute the sample standard deviations for the five groups. What is your conclusion about the ANOVA constant standard deviation assumption?
3. Use Minitab to carry out a 1-way ANOVA for this data, with Tukey Comparisons. Based on this test (and assuming it to be valid), state your conclusions about these pesticide methods.

Marketing Plan

The Company hired you as Marketing Manager of Saudi Arabian Region for "Canon" Company to start its activities in Saudi Arabia.

You have to establish a marketing department starting from the Analysis of the market, formulate overall marketing goals, objectives, strategies, and tactics within the context of an organization's business, mission, and goals designing and planning the entire function.

Write a Marketing Plan considering the following points

1. Introduction, Goals and Objectives

To introduce this section you should include the "mission statement" of the business; an idea of what its goals are for customers, clients, employees and the consumer.

1. Introduction about the business.
2. Business vision and mission
3. Business objective.
4. Products and services offered

2. Environmental Analysis

Conduct an environmental analysis that looks at and comments on your local area and your network of business contacts, competitors and customers.

3. Target Market Analysis

Identify the target market, describing how the company will meet the needs of the consumer better than the competition does.

There is a debate about whether sterile hypodermic needles should be passed out free of charge
in British Columbia. Proponents argue that doing so will reduce the incidence of diseases, such
as HIV/ Hepatitis, that are often spread by needle sharing among drug users. Opponents believe
the doing so will encourage more drugs use by reducing the risks of this behaviour. As an
economist asked to assess the policy you must know the following: (a) how responsive the
spread of diseases like HIV/ Hepatitis is to the price of sterile needles and (b) how responsive
drug use is to the price of sterile needles. Assuming that you know these two things, use the
concept of price elasticity of demand for sterile needles and the cross-price elasticity between
drugs and sterile needles to answer the following questions.
(i) In what circumstances do you believe this is a beneficial policy? Explain
(ii) In what circumstances do you believe this is a bad policy? Explain.

1. What is the independent variable (X) and what is the dependent variable (y)

B. Write a null and alternative hypothesis statement

C. What is the R-squared value and interpret it’s meaning?

D. What is the correlation coefficient and interpret it’s meaning?

E. Predict the receipts for a movie that has a Twitter activity of 100,000 using the linear regression formula generated after you run the regression analysis in Excel (just like we did in the lecture notes)

F. At the 95% significance level, is there significant evidence of a relationship between Twitter activity and receipts?

G. Do you accept or reject the null hypothesis?

H. Based upon your answers above, provide us with a paragraph (3-4 sentence) conclusion that would be appropriate to explain the results to a senior executive that isn’t as familiar with statistics as you are!

The maximum discount value of the Entertainment® card for the "Fine Dining" section for various pages is given in the table below.

Let page number be the independent variable and maximum value be the dependent variable.

a) Calculate the least-squares line. Put the equation in the form of: ŷ = a + bx. (Round your answers to three decimal places.)

ŷ = (?)  + (?) x

b) Find the correlation coefficient. (Round your answer to four decimal places.)

r =
Is it significant? (Use a significance level of 0.05.)

Yes

No  

c) Find the estimated maximum values for the restaurants on page ten and on page 70. (Round your answers to the nearest cent.)

d) Does it appear that the restaurants giving the maximum value are placed in the beginning of the "Fine Dining" section? How did you arrive at your answer?

Yes, there is a significant linear correlation so it appears there is a relationship between the page and the amount of the discount.

No, there is not a significant linear correlation so it appears there is no relationship between the page and the amount of the discount.    

e) Suppose that there were 200 pages of restaurants. What do you estimate to be the maximum value for a restaurant listed on page 200? (Round your answer to the nearest cent.) (?)

f) Is the least squares line valid for page 200? Why or why not?

Yes, the line produced a valid response for the maximum value.

No, using the regression equation to predict the maximum value for page 200 is extrapolation.  

g) What is the slope of the least-squares (best-fit) line? (Round your answer to three decimal places.)
(?) Interpret the slope.

As the page number increases by one page, the discount decreases by how much?
