Using the Central Limit Theorem · Exercise 41
For each problem, wherever possible, provide graphs and use a calculator.
Men have an average weight of 172 pounds with a standard deviation of 29 pounds.
(a) Find the probability that 20 randomly selected men will have a sum weight greater than 3,600 pounds.
(b) If 20 men have a sum weight greater than 3,500 pounds, then their total weight exceeds the safety limits for water taxis. Based on (a), is this a safety concern? Explain.
