10.2 California Imaging Center, a not-for-profit business, is evaluating the purchase of new diagnostic equipment. The equipment, which costs $600,000 has an expected life of five years and an estimated salvage value of $200,000 at that time. The equipment is expected to be used 15 times a day for 250 days a year for each year of the project’s life. On average, each procedure is expected to generate $80 in cash collections during the first year of use. Thus, net revenues for Year 1 are estimated at 15 X 250 X $80 =$300,000. Labor and maintenance costs are expected to be $100,000 during the first year of operation, while utilities will cost another $10,000 and cash overhead will increase by $5,000 in Year 1. The cost for expendable supplies is expected to average $5 per procedure during the first year. All costs and revenues are expected to increase at 5 percent inflation rate after the first year. The center’s corporate cost of capital is 10 percent. a. Estimate the project’s net cash flows over its five-year estimated life. (hint: use the following format as a guide.) Year 0 1 2 3 4 5 Equipment Cost Net revenues Less: labor/maintenance costs Utilities cost Supplies Incremental overhead Operating income Equipment salvage value Net cash flow b. What are the project’s NPV and IRR? (Assume for now that the project has average risk.) c. Assume the project is assessed to have high risk and California Imaging Center adds or subtracts 3 percentage points to adjust for project risk. Now, what is the project’s NPV? Does the risk assessment change how the project’s IRR is interpreted?

) An aluminum wire (1 inch in diameter, 1000 m long) is used to pull a cable car up a mountain. If the weight of the unloaded cable car is 1 ton, and if there are 6 people in the car, and each weighs an average of 150 pounds: a) calculate the stress (in pounds per sq. inch), b) calculate the strain of the wire when it begins to lift the cable car, c) calculate the change in length of the cable. d) determine the change in the diameter of the wire (Poisson’s ratio is 0.31 for Al) – be sure to indicate the proper sign (positive for increase, negative for decrease) State your assumptions. EAl = 10 x 106 psi (pounds per square inch). [hint: be careful with the units]

Researchers recently investigated whether or not coffee prevented the development of high blood sugar (hyperglycemia) in laboratory mice. The mice used in this experiment have a mutation that makes them become diabetic. Read about this research study in this article published on the Science Daily web-site New Evidence That Drinking Coffee May Reduce the Risk of Diabetes as well as the following summary: A group of 11 mice was given water, and another group of 10 mice was supplied with diluted black coffee (coffee:water 1:1) as drinking fluids for five weeks. The composition of the diets and living conditions were similar for both groups of mice. Blood glucose was monitored weekly for all mice. After five weeks, there was no change in average body weight between groups. Results indicated that blood glucose concentrations increased significantly in the mice that drank water compared with those that were supplied with coffee. Finally, blood glucose concentration in the coffee group exhibited a 30 percent decrease compared with that in the water group. In the original paper, the investigators acknowledged that the coffee for the experiment was supplied as a gift from a corporation. Then answer the following questions in your own words: 1. Identify and describe the steps of the scientific method. Which observations do you think the scientists made leading up to this research study? Given your understanding of the experimental design, formulate a specific hypothesis that is being tested in this experiment. Describe the experimental design including control and treatment group(s), and dependent and independent variables. Summarize the results and the conclusion (50 points) 2. Criticize the research described. Things to consider: Were the test subjects and treatments relevant and appropriate? Was the sample size large enough? Were the methods used appropriate? Can you think of a potential bias in a research study like this? What are the limitations of the conclusions made in this research study? Address at least two of these questions in your critique of the research study (20 points). 3. Discuss the relevance of this type of research, both for the world in general and for you personally (20 points). 4. Write answers in your own words with proper grammar and spelling (10 points)
