Suppose that X is a Poisson random variable with 2 = 9. Round your answers to 3 decimal places (e.g. 98.765). (a) Compute the exact probability that X is less than 6. 0.116 (b) Use normal approximation to approximate the probability that X is less than 6. Without continuity correction: 0.159 With continuity correction: 0.121 (c) Use normal approximation to approximate the probability that 12 < X < 18. Without continuity correction: 0.157 With continuity correction: i
