Chapter 4.4, Problem 34E
The U.S. Department of Transportation reported that during November, 83.4% of Southwest Airlines’ flights, 75.1% of US Airways’ flights, and 70.1% of JetBlue’s flights arrived on time (USA Today, January 4, 2007). Assume that this on-time performance is applicable for flights arriving at concourse A of the Rochester International Airport, and that 40% of the arrivals at concourse A are Southwest Airlines flights, 35% are US Airways flights, and 25% are JetBlue flights.
- a. Develop a joint
probability table with three rows (airlines) and two columns (on-time arrivals vs. late arrivals). - b. An announcement has just been made that Flight 1424 will be arriving at gate 20 in concourse A. What is the most likely airline for this arrival?
- c. What is the probability that Flight 1424 will arrive on time?
- d. Suppose that an announcement is made saying that Flight 1424 will be arriving late. What is the most likely airline for this arrival? What is the least likely airline?
