A new concept hospital, one that is mobile and will serve remote areas, has received initial certification from the Ministry of Health to become a centre for liver transplants. The hospital, however, must complete its first 18 transplants under great scrutiny and with no additional transfer payments from the Ministry. The very first transplant, just completed, required 30 hours. On the basis of research at the hospital, management estimates that it will have an 80% learning curve. Estimate the time it will take to complete:
a) The 5th liver transplant.
b) All of the first 5 transplants.
c) The18thtransplant.
d) All 18 transplants.
