A small airplane always flies with 100 passengers. Assume that the population of travelers weigh on average 180 lbs with Standard deviation of 7lb. if the airplane can't carry more than 18,200 lbs of passenger-weight, find the propability a random flight will be over capacity. Show work!!

A (fictional) study finds that airline passenger weigh an average of 185lb with standard deviation of 25b. It also finds they bring an average of 25b of luggage, with a standard deviation of 10b. Assume these weights are independent. If a flight has 180 passengers then: (a) The airline needs to estimate (in advance) the total weight of passengers and their bags. Find the expectation and standard deviation of this. (b) The airline will use this to predict how much...

2. An airplane with room for 100 passengers has a total baggage limit of 6000 lb. Suppose that the total weight of the baggage checked by an individual passenger is a non-normal random variable x with a mean value of 55 lb anda standard deviation of 17 lb. Describe the sampling distribution of the sample mean by filling in the spaces below: What is the probability that the total weight of their baggage will exceed the weight limit? (Make sure...

Offwefly Airlines has a daily flight from Sacramento to Las Vegas with a capacity of 100 passengers. On average, 18 ticket holders cancel their reservations at the last minute, so the company intentionally overbooks the flight. Cancellations can be described by a normal distribution with a standard deviation of 2.2. Profit per passenger is $189. If a passenger arrives but cannot board due to overbooking, the company policy is to provide compensation of $131. What is the optimal probability of...

Because of safety considerations, in May 2003 the Federal Aviation Administration (FAA) changed its guidelines for how small commuter airlines must estimate passenger weights. Under the old rule, airlines used 180 pounds as a typical passenger weight (including carry-on luggage) in warm months and 185 pounds as a typical weight in cold months. A journal reported that an airline conducted a study to estimate average passenger plus carry-on weights. They found an average summer weight of 183 pounds and a...

Central Limit Theorem application: In product design for human use and recommended guideline for the product’s human use, it is important to consider the weights of people so that airplanes or elevators aren’t overloaded. Based on data from the National Health Survey, the weight of adults in the United States has a mean of 181 pound (the average of 195.5 for males and 166.2 for females, assuming, arbitrarily, equal male and female population) with a standard deviation of 30 pounds....

In the library on a university campus, there is a sign in the elevator that indicates a limit of 16 persons. Furthermore, there is a weight limit of 2500 lb. Assume that the average weight of students, faculty, and staff on campus is 151 lb, that the standard deviation is 26 lb, and that the distribution of weights of individuals on campus is approximately normal. If a random sample of 16 persons from the campus is to be taken: (a)...
