Question:
A random variable, W, has first two moments given as follows: E [W] = 3 hours and E [W2 ] = 10.5 Consider a Poisson process, N = {N(t) : t ≥ 0}, such its first arrival time has E [S1] = 7.5 minutes. Assume that the process does not depend on W. Introduce a random variable, Y, such that Y = N(W).
1. Find the expected value of Y
2. Determine variance of Y
