A study examined the impact of depression on a patient’s ability to survive cardiac disease. Researchers identified 450 people with cardiac disease, evaluated them for depression, and followed the group for 4 years. Of the 361 patients with no depression, 67 died. Of the 89 patients with minor or major depression, 26 died. Among the patients who suffer from cardiac disease, are depressed patients more likely to die than non-depressed ones? a. Write appropriate hypotheses. b. Test your hypothesis and state your conclusion. c. Explain in this context what your P-value means. d. If your conclusion is actually incorrect, which type of error did you commit?

For the initial scenario, assume your current age, zero current savings, a retirement age of 60, a life expectancy of 95 years, an inflation rate of 3.5%, an investment portfolio return of 9% and current purchasing power of income of $75,000. Set up your worksheet to compute and show the user: (a) How much they will need to have the day they retire in order to fund their retirement with no additional contributions, (b) How much they will need to invest in the fund each year until retirement to reach that goal.

do a second scenario with retirement age of 70 and make a text section in which you explain the differences between retiring at age 60 and waiting until age 70. Which would you personally prefer and why? How will your choice affect your investing strategy for the next 20 years?

1. Given the following set of grades from a recent statistics exam:

a) (5 points) Sketch the histogram of the data.  You may either sketch it by hand or give a screenshot of Statkey.

b) (6 points) Describe the shape of the data. Describe the modality, symmetry, and any unusual features, e.g., outliers.

c) (5 points) State the Five Number Summary of the data, including labeling what each number represents.

d) (4 points) State the best measure for the center and spread. Explain your answers.

Two intracellular molecules A and B, are normally synthesized at a constant rate of 1000 molecules per second per cell. The degradation rate of A is 0.01/s and B is 0.1/s

A}Write a differential equation to describe how the number of molecules of A and B change over time

B}What is the steady state value of A and B? How many molecules of A and B will there be after 1 second at steady state?

C}If the rate of synthesis of both A and B were suddenly increased 10-fold to 10,000 molecules per second—without any change in their degradation rate—how many molecules of A and B would there be after one second?

D}Which molecules would be preferred for responding rapidly changing environment? Explain your answer

The psychiatric nurse is initiating an interview with Mr. Johnson. He is a 33-year-old male patient admitted to the Behavioral Center with a diagnosis of schizophrenia. The nurse begins the interaction by saying, “What shall we talk about today?” (Learning Objective: 2)

a. Explain why this is an appropriate opening statement to initialize a clinical interview session.

b. Why should the nurse use simple, concrete, and direct messages with the patient?

Write an explanation of one of Feldman's Free Lunch cases and why it shows that the original formulation of Utilitarianism is imperfect. You will want to walk through the examples slowly in order to explain why Utilitarianism concludes what it does about the situation and why that is counterintuitive. You may use Feldman's made up numbers to illustrate the case, but you do not need to draw any graphs or tables. (~ 1 page)​
