Suppose the incidence rate of myocardial infarction (MI)
was 5 per 1000 among 45- to 54-year-old men in 2000.
To look at changes in incidence over time, 5000 men in this
age group were followed for 1 year starting in 2010. Fifteen
new cases of MI were found
7.12 Using the critical-value method with α = .05, test
the
hypothesis that incidence rates of MI changed from 2000
to 2010.
7.13 Report a p-value to correspond to your answer to
Problem 7.12.
Suppose that 25% of patients with MI in 2000 died within
24 hours. This proportion is called the 24-hour case-fatality
rate.
7.14 Of the 15 new MI cases in the preceding study,
5 died within 24 hours. Test whether the 24-hour casefatality
rate changed from 2000 to 2010.
7.15 Suppose we eventually plan to accumulate 50 MI
cases during the period 2010–2015. Assume that the
24-hour case-fatality rate is truly 20% during this period.
How much power would such a study have in distinguishing
between case-fatality rates in 2000 and 2010–2015 if a
two-sided test with significance level .05 is planned?
7.16 How large a sample is needed in Problem 7.15 to
achieve 90% power?

LP2.2 Assignment: Patient Care Partnership
In the past two Learning Plans you've studied various codes that can govern the behavior of healthcare administrators, including the ACHE Code of Ethics, the Patient Care Partnership, and the ethical theorists you encountered in Learning Plan 1. In this assignment, you'll apply the codes and theories you've learned about to the following healthcare management dilemma.
You are the healthcare manager in a university medical center. After an inspection, JCAHO, your accreditor, notes that patient satisfaction surveys give you a low rating. Although your hospital has a great track record for disease detection, treatment, and monitoring, patients routinely rate their experience at and satisfaction with the hospital as low.
In follow-up interviews with patients, JCAHO discovers that patients felt they and their families were not well-informed about upcoming procedures and options. They had a general feeling of uncertainty about their care and treatment. One former patient stated, "The doctor spent more time talking with the medical residents and student nurses than with me!"
Answer each of the following questions in a paragraph of 5-7 sentences (for a total of 4 paragraphs):
Which ethical principles would you apply to this scenario? Which ethical theorists would you use to guide you? Refer to your textbook, putting all direct citations in quotes.
Which parts of the AHA's Patient Care Partnership document would you apply to this scenario? Refer to specific parts of the document, putting all direct citations in quotes.
Which parts of the ACHE Code of Ethics would you apply to this scenario? Refer to specific parts of the document, putting all direct citations in quotes.
Describe an "action plan" to present to the accrediting body (JCAHO) to convince them you're serious about improving your patient satisfaction scores.

STEP 1:
Convert the above to 1NF
STEP 2:
Consider the following functional dependencies of the invoice data:
OrderID à OrderDate, CustomerNum, CustomerName, CustomerAddress
ProductID à ProductDescription, ProductFinish, ProductStandardPrice
STEP 3:
Convert your 1NF table to 2NF. (i.e., look only at non-key attributes that are dependent on a single PK)
A relation is in 2NF if it contains no partial functional dependencies.
STEP 4:
Now, you’ve realized there are some additional functional dependencies:
CustomerNum à CustomerName, CustomerAddress
Convert your 2NF relations to 3NF based on the dependencies you just received.
