United Airlines established a discount airline named Ted. The managers were interested in determining how flyers using Ted rate the airline service. They plan to question a random sample of flyers from the November 12 flights between Denver and Fort Lauderdale. A total of 578 people were on the flights that day. United has a list of the travelers together with their mailing addresses. Each traveler is given an identification number (here, from 001 to 578). Use Excel to generate a list of 40 flyer identification numbers so that those identified can be surveyed.
