\n(b) To what age would you expect a person to live (on average) once he\/she attained the age of 15 years? [3 marks]
\nQuestion 2 [25 marks]:
\nA large hospital in Nepal followed up with men with prostate cancer for 15 years. The data is summarised in two tables below, differentiating patients according to treatment status (With and without chemotherapy) and providing the necessary information to calculate the cumulative survival probabilities.

\n(b)<\/p>\n
To what age would you expect a person to live (on average) once he\/she attained the age of 15 years?<\/p>\n
The expected age of survival for a person who has reached the age of 15 is 14 years. This is calculated by taking the sum of the expected ages of survival for each year after the age of 15.<\/p>\n
The expected age of survival for each year after the age of 15 is calculated by dividing the number of people who are alive at the beginning of the year by the number of people who die during the year.<\/p>\n
For example, the expected age of survival<\/p>\n","protected":false},"excerpt":{"rendered":"
