An airline company is interested in the opinions of their frequent flyer customers about their proposed new routes. Specifically, they want to know what proportion of them plan to use one of their new hubs in the next 6 months. They take a random sample of 20,000 from the database of all frequent flyers and send them an e-mail message with a request to fill out a survey in exchange for 2500 miles. Address the questions that relate to the population sampling process, sampling frame, sample process and the population parameter of interest.
