Basic Math

Most major airlines allow passengers to carry two pieces ofluggage (of a certain maximum size) onto the plane. However, theirstudies show that the more carry-on baggage passengers have, thelonger it takes the plane to unload and load passengers. Oneregional airline is considering changing its policy to allow onlyone carry-on per passenger. Before doing so, the airline decided tocollect some data. Specifically, a random sample of 1000 passengerswas selected. Researchers observed the passengers and noted thenumber of bags each person carried on the plane. Out of the 1000passengers, 340 had more than one bag.

  1. Based on this sample, develop and interpret a 99% confidenceinterval estimate for the proportion of the traveling populationthat would have been impacted had the “one-bag” limit been ineffect. Discuss your result.

  2. The domestic version of Boeing’s 757 has a capacity for 220passengers. Determine an interval estimate of the number ofpassengers you would expect to board the plane with more than onecarry-on. Assume the plane is at its passenger capacity.
