For example, the chances of survival begin in interval one as 6/6, then are 5/6 in interval two, and 4/5 for interval three giving a cumulative survival rate (probability) in interval three of 6/6 × 5/6 × 4/5 = 0.667. how many chambers does the heart have quizletWebNext ignore the rows with no cumulative hazard value and plot column (1) vs column (6).
