You are preparing a presentation for your classmates regarding the clinical care coordination conference for a patient with terminal cancer. As part of the preparation you have your classmates read the Nursing Code of Ethics for Professional Registered Nurses. Your instructor asks the class why this document is important. Which of the following statements best describes this code?

1. Improves self–health care
2. Protects the patient's confidentiality
3. Ensures identical care to all patients
4. Defines the principles of right and wrong to provide patient care

Mills's biology class conducted an experiment to investigate the impact of different light regimens on the growth of radish plants. They randomly assigned 60 2-day-old plants in identical pots to three treatments. Twenty plants were exposed to artificial "grow-light" lamps for 8 hours per 24-hour period, 20 plants were exposed to the same light for 16 hours, and 20 plants were exposed to light for the entire 24-hour period. All plants were grown in the same room at $24^{\circ} \mathrm{C},$ and all were given the same amount of water every other day. After 20 days, the mean weight of the 16-hour plants was higher than the mean weight of the 8-hour and 24-hour plants. Identify one variable that the class kept the same in this experiment.

An important challenge in clinical trials in patients who drop out before the trial is completed. This can cost pharmaceutical companies millions of dollars because patients who have obtained a tested treatment for months must be combined with those who obtained it for a much shorter time. Can we predict who will drop out of a study early? We have data for 428 patients from a clinical trial of depression. We have data on their Age, their Hamilton Rating Depression Scale (HRDS), and whether or not they completed the study (Drop $1=\text{Yes}; 0=N$. Completed the study).

Here is the output from a logistic regression model of the Drop in HRDS and Age.

a) Write out the estimated regression equation.

The following set of data values was acquired from a study of people's perceptions of whether the color of a person's clothing is related to how intelligent the person looks. The subjects rated the person's intelligence on a scale of 1 to 10. Randomly chosen group 1 subjects were shown people with clothing in shades of blue and gray. Randomly chosen group 2 subjects were shown people with clothing in shades of brown and yellow. Randomly selected group 3 subjects were shown people with clothing in shades of pink and orange. The results follow.

Are there any contradictions in the results?

The Gompertz model is y'=Aylny(A>0), where y(t) is the mass of tumor cells at time t. The model agrees well with clinical observations. The declining growth rate with increasing y>1 corresponds to the fact that cells in the interior of a tumor may die because of insufficient oxygen and nutrients. Use the ODE to discuss the growth and decline of solutions (tumors) and to find constant solutions. Then solve the ODE.

An institutional review board (IRB) has approved the use of an experimental cancer vaccine in a clinical trial. Patients with advanced disease who had received standard treatments with no success were the subjects. Of the 94 subjects who received the vaccine, 26 died during the study. Their deaths were not due to the vaccine. Some family members of the subjects sued the hospital, the study director, the company that made the vaccine, a university official, individual members of the IRB, and the university bioethicist who consulted with the $\operatorname{IRB}$. Discuss this case from the point of view of ethics. Discuss any additional information that you would need to form your opinion.

The University of Cincinnati Center for Business Analytics is an outreach center that collaborates with industry partners on applied research and continuing education in business analytics. One of the programs offered by the Center is a quarterly Business Intelligence Symposium. Each symposium features three speakers on the real-world use of analytics. Each corporate member of the center (there are currently ten) receives five free seats to each symposium. Nonmembers wishing to attend must pay $75 per person. Each attendee receives breakfast, lunch, and free parking. The following are the costs incurred for putting on this event:

Rental cost for the auditorium$150

Registration processing $8.50 per person

Speaker costs 3@$800 = $2,400

Continental breakfast$4.00 per person

Lunch $7.00 per person

Parking$5.00 per person

Build a spreadsheet model that calculates a profit or loss based on the number of nonmember registrants.

To compensate for weightlessness in a space station, artificial gravity can be produced by rotating the station. ${ }^8$ The required number $N$ of rotations per minute is a function of two variables: the distance $r$ to the center of rotation, and $a$, the desired acceleration (or magnitude of artificial gravity). See Figure $2.58$ on the following page. The formula is

$$N=\frac{30}{\pi} \times \sqrt{\frac{a}{r}} .$$

We measure $r$ in meters and $a$ in meters per second. a. First we suppose that we want to simulate the gravity of Earth, so $a=9.8$ meters per second. i. Discover a formula for the needed number $N$ of rotations per minute as a function of the distance $r$ to the center of rotation. i. Create a graph of $N$ versus $r$. Include distances from 10 to 200 meters. iii. What happens to the needed number of rotations per minute as the distance increases? Describe your answer in practical terms. iv. What number of rotations per minute is necessary to produce Earth's gravity if the distance to the center is 150 meters? b. We suppose that the distance to the center is 150 meters (so $r=150$ ). i. Discover a formula for the required number $N$ of rotations per minute as a function of the desired acceleration $a$. ii. Create a graph of $N$ versus $a$. Include values of $a$ from $2.45$ (one-quarter of Earth's gravity) to $9.8$ meters per second. iii. What happens to the needed number of rotations per minute as the desired acceleration increases?

Cycle II of the Health Examination Survey used a nationwide probability sample of children age 6 to 11. One subject of the survey was to study the relationship between the children's scores on intelligence tests and the family backgrounds. The WISC vocabulary scale was used. This consists of 40 words which the child has to define; 2 points are given for a correct answer, and 1 point for a partially correct answer. There was some relationship between tests scores and the type of community in which the parents lived. For example, big-city children averaged 26 points on the test, and their SD was 10 points. But rural children only averaged 25 points with the same SD of 10 points. Can this difference be explained as a chance variation? You may assume that the investigators took a simple random sample of 400 big-city children, and an independent simple random sample of 400 rural children.

An Act to provide for an exchange of lands with the Indians residing in any of the states or territories, and for their removal west of the river Mississippi.

Be it enacted by the Senate and House of Representatives of the United States of America, in Congress assembled, That it shall and may be lawful for the President of the United States to cause so much of any territory belonging to the United States, west of the river Mississippi, not included in any state or organized territory, and to which the Indian title has been extinguished, as he may judge necessary, to be divided into a suitable number of districts, for the reception of such tribes or nations of Indians as may choose to exchange the lands where they now reside, and remove there; and to cause each of said districts to be so described by natural or artificial marks, as to be easily distinguished from every other ...
