Using MGF
11. (5 marks) Two customers, Bob and Mary, arrive at an occupied service counter at the same time Bob insists Mary go ahead of him. Let X denote the time (in minutes) until Mary can be served and y be the time (in minutes) until Bob is served. Suppose the joint density of X and Y is 0 otherwise Find the moment-generating function of U =-aln(X/Y), what is the distribution of U?

Can you solve 12
Thus, the expected time waiting is 5/6 hours (or 50 minutes) (Note that it is wrong to reason like this: Alice expects to arrive at 12:30, Bob expects to arrive at 1:00: thus, we expeet that Bob will wait 30 mimutes for Alice.) (b). We want to compute the probability that Bob has to wait for Alice, which is P(Y < X), which we do by integrating the joint density, f(r,y), over the region where <...

13. (5 marks) In order for a device to run, two batteries must both be functional. Let X be the lifetime of battery 1, and Y be the lifetime of battery 2, both measured in days. Suppose the joint density of X and Y is given as f(x, y)-po 0 , otherwise If you just turned on the device with these new batteries, what is the expected life of the machine? That is, what the expected time to wait until...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...

CASE 20 Enron: Not Accounting for the Future* INTRODUCTION Once upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant "E" slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm...
