Question description
The weight of people in a small town in Missouri is known to be normally distributed with a mean of 188 pounds and a standard deviation of 29 pounds. On a raft that takes people across the river, a sign states, “Maximum capacity 3,600 pounds or 18 persons.” What is the probability that a random sample of 18 persons will exceed the weight limit of 3,600 pounds? Use Table 1. (Do not round intermediate calculations. Round "z" value to 2 decimal places and final answer to 4 decimal places.) |
