Question: For the survival data given below, with "+" indicating censored subjects.

22, 2, 48, 85, 160, 238, 56+, 94+, 51+, 12, 171, 80, 180, 4, 90, 180+, 3. Part a): Let S(t) and S(t) denote the Kaplan-Meier estimator and the Fleming- Harrington estimator of the survivorship function of the event time, respectively. Calculate S(100) and S(100) by hand. What is the standard error of S(100)? Part b): What is the standard error of S(100)
