a. Using the data from the table, calculate for all deaths: 1. The probability of survival beyond the time when each death occurred 2. The cumulative probabilities of survival
Added by Quame E.
Step 1
- For death E: - Total deaths after E = 4 (E, F, G, H) - Probability of survival beyond E = 4/8 = 0.5 - For death F: - Total deaths after F = 3 (F, G, H) - Probability of survival beyond F = 3/7 ≈ 0.4286 - For death G: - Total deaths after G = 2 (G, H) Show more…

Take a look at the table, below. How can you use the data in the table to calculate the probability of surviving each year of treatment, given survival of the previous treatment year? How can you calculate the probability of surviving all five years? How about the probability of surviving other numbers of treatment years?
