Suppose the survival times (in months since transplant) for eight patients who received bone marrow transplants are 3.0, 4.5, 6.0, 11.0, 18.5, 20.0, 28.0, and 36.0. Assume no censoring.
a. What is the median survival time?
b. What is the mean survival time?
c. Using 5 months as the interval, construct a life table for these data.
