A group of 12 hemophiliacs, all under 41 years of age at the time of HIV seroconversion, were followed from primary AIDS diagnosis until death (ideally, we should take as a starting point the time at which a person contracts AIDS rather than the time at which the patient is diagnosed, but this information is unavailable). Survival times (in months) from diagnosis until death of these hemophiliacs were: 2, 3, 6, 6, 7, 10, 15, 15, 16, 27, 30, and 32. Calculate the mean, geometric mean, and median.
