The following data are survival times in days from a life-threatening condition: 15, 18, 18, 21, 2lC, 25', 26. Graph the estimated S(t) by the Kaplan-Meier method using a computer program.

If we ignored the censored observations and the computed mean survival time using the usual formula for the mean and only the observations from those who died, would our estimate of the true mean be too large or too small?
