Suppose that weights of adults in North America have a skewed distribution with mean 80.7 kg and standard deviation 15.2 kg. A plane holds 50 passengers and has a passenger weight limit of 4,200 kg. What is the chance that the total weight of 50 passengers exceeds 4,200kg? (Hint: This is the same as the chance that the average weight of 50 people exceeds 4,200/50 = 84kg.) Please provide a complete and correct diagram.
