Chapter 9.3, Problem 66E

Medicine. The study discussed in Problem 65 also produced the following data for patients who underwent aortic valve replacements: each day $2\%$ of the patients in the ICU died, $60\%$ were transferred to the CCW, and the remainder stayed in the ICU. Furthermore, each day $5\%$ of the patients in the CCW developed complications and were returned to the ICU, $1\%$ died while in the CCW, $19\%$ were released from the hospital, and the remainder stayed in the CCW.

(A) In the long run, what percentage of the patients in the CCW are released from the hospital?

(B) In the long run, what percentage of the patients in the ICU die without ever being released from the hospital?

(C) What is the average number of days a patient in the CCW will stay in the hospital?
