Sketch hazard functions that would correspond to the following time-to-event random variables. (You may want to do a little background research.)
a. Lifetime of an individual measured from birth (don’t assume anything about the health or demographics of this person)
b. Time until death after surgery to remove a cancerous tumor
Be sure to label the time axis, and mark time points appropriately. Briefly explain your reasons for any changes in the shape of the hazard function over time.
