Using the Central Limit Theorem · Exercise 41

For each problem, wherever possible, provide graphs and use the 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 3600 lbs.
(b) If 20 men have a sum weight greater than 3500 lbs, then their total weight exceeds the safety limits for water taxis. Based on (a), is this a safety concern? Explain.

Its source prints no answer for this problem, so there's nothing to check against.
