In this hypothetical case study, a new rapid test kit nicknamed Alpha is being reviewed. The sensitivity of Alpha is 93.0% (0.93) and the specificity is 96.0% (0.96). Assume that the actual prevalence of the Zika antibody among the United States population of blood donors is 4% (0.04) and that of the hurricane disaster relief volunteers returning from Puerto Rico is 20.0% (0.20).

Construct a separate 2 x 2 table, to calculate the PPV and NPV for a population of 2,500 volunteers who aided in the recent hurricane relief efforts in the Caribbean.

If sensitivity and specificity remain constant, what is the relationship of prevalence to predictive-value positive and predictive-value negative? (Hint: Think if one increases, decreases, or stays the same.)

In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is 430 ly l y away, and that you want your 20,000 kg k g rocket to move so fast that you age only 38 years during the round trip.


How fast must the rocket travel relative to earth?


How much energy is needed to accelerate the rocket to this speed?


How many times larger is this energy than the total energy used by the United States in the year 2000, which was roughly 1.0×1020J1.0×1020J?

A large city hotel serves two types of customers/guests: general visitors (gv), and convention attendees (ca). Their respective daily demand functions are: For the general visitors segment Q gv = 1,400 – 10 Pgv, and for the convention attendees segment Qca = 2,400 -20 Pca. The marginal cost for serving an additional guest is the same, regardless of the type of customer, and the hotel’s daily Total Cost function is: T.C. = 18,200 + 30 Q.

  1. With price discrimination, how many rooms should this hotel offer to in each market segment, and what rate (price) should it charge to each group of customers?
  2. What would this hotel’s daily profits be?
  3. What would the mark-up, as a percentage of the membership price, be in each market segment?

From Martland (2012) 9.1 A dispute has broken out in a board meeting of a real estate investment firm. Mr. Park advocates developing a site as a parking lot that would require a minimal level of investment, produce revenues of close to $1 million per year, and have an IRR of more than 40%. Mr. Macy prefers a mixed development with several small stores at street level and apartments on the upper levels. He argues that the project will have a NPV of $6 to $10 million, using the company’s hurdle rate of 15%. ‘‘Fine,’’ says Mr. Park, ‘‘but your IRR is still less than 20%, so my project is better.’’ Which project would you support? and why?

1. You decide to purchase a van to transport your hotel guests to and from the airport. This is a new service you are adding to your hotel because you have noticed from your STR reports that your competitors are having better occupancy percentages and slightly better ADRs. And after some research, you do have a very comparable product but your current guests have also put in their comment cards that they wish you would provide airport transportation. The cost of the van with the upgrades totals $75,000. You are not charging your guests anything but you have estimated that this new service, you should have an increase in your annual cash flow of $28,000 for the next 5 years. What is the IRR of this van?
