'Problem 7: A plane carries 400 people assume that the average weight of person is 170 pounds with standard derivation of 30 pounds What is the probability that the total weight of people Ssoo will be between 68500 pounds and 69000 pounds? What is the probability that the total weight Will be more than 69500 pounds? Find the maximum number of people the plane can carry ifthe probability that the total weight is less than 70000 pounds must be at least 0.69152'

Step 1
Find the mean and standard deviation of the total weight of people on the plane: Mean = 400 x 170 = 68,000 pounds Standard deviation = sqrt(400) x 30 = 600 pounds Show more…

Suppose that the average weight of males is 170 pounds with a standard deviation of 30 pounds. If there are 100 men on a plane, find the probability that the total weight of the men on the plane exceeds 18,000 pounds. (Hint: First, find what the average weight for 100 males must be to exceed 18,000 pounds.)

The baggage limit for an airplane is set at 100 pounds per passenger. Thus, for an airplane with 200 passenger seats, there would be a limit of 20,000 pounds. The weight of the baggage of an individual passenger is a random variable with a mean of 95 pounds and a standard deviation of 35 pounds. If all 200 seats are sold for a particular flight, what is the probability that the total weight of the passengers' baggage will exceed the 20,000-pound limit?
