Question: 6.1.2 A pure birth process starting from X.0/ D 0 has birth parameters 0 D 1; 1 D 3;2 D 2, and 3 D 5.
6.1.2 A pure birth process starting from X.0/ D 0 has birth parameters 0 D 1;
1 D 3;2 D 2, and 3 D 5. Let W3 be the random time that it takes the process to reach state 3.
(a) Write W3 as a sum of sojourn times and thereby deduce that the mean time is E[W3] D 11 6 .
(b) Determine the mean of W1 CW2 CW3.
(c) What is the variance of W3?
