Question:

IEEE Transactions (June 1990) presented a hybrid algorithm for solving polynomial 0–1 mathematical programming problems. The solution time (in seconds) for a randomly selected problem solved using the hybrid algorithm has a normal probability distribution with mean μ = .8 second and σ = 1.5 seconds. Consider a random sample of n = 30 problems solved with the hybrid algorithm.

a. Describe the sampling distribution of S2, the variance of the solution times for the 30 problems.

b. Find the approximate probability that S2 will exceed 3.30.
