The weight of people in a small town in Missouri is known to be normally distributed with a mean of 176 pounds and a standard deviation of 29 pounds. On a raft that takes people across the river, a sign states, “Maximum capacity 3,383 pounds or 17 persons.” What is the probability that a random sample of 17 persons will exceed the weight limit of 3,383 pounds? (You may find it useful to reference the z table. Do not round intermediate calculations. Round final answer to 2 decimal places.)   probability=   ANSWER IS NOT 0.0054, 0.005, or 0.1
