Problem 3. Survival times in years) are given for two study groups, each with 25 participants. Group 1 has no history of chronic disease (CHR = 0), and group 2 has a positive history of chronic disease (CHR = 1): Group 1 (CHR = 0): 11.3+. 6.4, 8.5, 13.7+, 10.1, 10.0, 5.7, 8.2, 2.0, 12.0. 9.9, 13.6+, 8.8, 2.2, 1.6, 10.2, 10.7, 11.1+, 5.3, 2.5, 10.6, 2.5, 5.7, 4.8, 2.7 Group 2 (CHR = 1): 4.8, 2.9, 10.7, 9.3, 9.1, 3.9, 5.0, 1.2, 4.4, 12.0, 2.9, 1.2, 6.9, 1.4, 3.0, 3.9, 3.5, 6.5, 9.9, 3.6, 5.2, 9.8, 6.8, 4.7, 3.9 (a) Complete the following survival tables for both Group 1 and Group 2: to my R(top) Group 1: 0.0 0 0 1 1.6 25 persons survive > 0 weeks 0 25 persons survive > 1.6 weeks 3 to my R(t) Group 2: 0.0 1.2 0 2 0 0 25 persons survive > 0 weeks 25 persons survive > 1.2 weeks (b) Compute the average survival time (T) and the average hazard rate (h) for each group. (c) Based on the your answer in b), briefly explain which group has better overall survival prospects. What might be the problem with your argument?
