Question 1: Using R- Estimate the survival function at 12 weeks, and 50 weeks post surgery. Find the standard errors of the estimates. Plot the Kaplan- Meier estimate.

Question 2: Estimate the cumulative hazard rate at 50 weeks, and find the standard error of your estimate. Estimate S(50) using the cumulate hazard estimate.

Compare the results with Question 1.
