Homework Answers
a) estimated total weight =(185+25)*180=37800
estimated standard deviation =sqrt((252+102)*180)=361.25
b)for 2.5 % top values are 2 standard deviaiton above from mean
therefore
there is a 2.5 % chance that the total weight will be 37800+2*361.25 =38522.50 or higher

Draw and clearly label a diagram of the normal distribution An airline knows that the mean weight of all pieces of passengers’ luggage is 49.7 lb with a standard deviation of 8.2 lb. What is the probability that the weight of 67 bags in a cargo hold is more than the plane’s total weight capacity of 3,600 lb?

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!!

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...

2.38 Baggage fees: An airline charges the following baggage fees: $25 for the first bag and $35 for the second. Suppose 52% of passengers have no checked luggage, 27% have only one piece of checked luggage and 21% have two pieces. We suppose a negligible portion of people check more than two bags. a) The average baggage-related revenue per passenger is: $ (please round to the nearest cent) b) The standard deviation of baggage-related revenue is: $ (please round to...

Airlines compute the weight of outbound flights using either standard average weights provided by the Federal Aviation Administration (FAA) or weights obtained from their own sample surveys. The FAA standard average weight for a passenger's carry-on items (personal items plus carry-on bags) is 16 pounds. Many airline companies have begun implementing fees for checked bags. Economic theory predicts that passengens will respond to the increase in the price of a checked bag by substituting carry-on bags for checked bags. As...

2. (15.36) In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average 190 pounds in the summer, including clothing and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 41.9 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 22 passengers. What...
