Chapter 4.4, Problem 34E
The Bureau of Transportation Statistics reports on-time performance for airlines at major U.S. airports. JetBlue, United, and US Airways share Terminal C at Boston's LoganAirport. The percentage of on-time flights reported for a sample month were 76.8% for JetBlue, 71.5% for United, and 82.2% for US Airways. Assume that 30% of the flights arriving at Terminal Care JetBlue flights, 32% are United flights, and 38% US Airways flights.
- Develop a joint
probability table with three rows (the airlines) and two columns (on-time and late). - An announcement is made that Flight 1382 will be arriving at gate 20 of Terminal C. What is the probability that Flight 1382 will arrive on time?
- What is the most likely airline for Flight 1382? What is the probability that Flight 1382 is by this airline?
- Suppose that an announcement is made saying that Flight 1382 will now be arriving late. What is the most likely airline for this flight? What is the probability that Flight 1382 is by this airline?

- iid 1. The CLT provides an approximate sampling distribution for the arithmetic average Ỹ of a random sample Y₁, . . ., Yn f(y). The parameters of the approximate sampling distribution depend on the mean and variance of the underlying random variables (i.e., the population mean and variance). The approximation can be written to emphasize this, using the expec- tation and variance of one of the random variables in the sample instead of the parameters μ, 02: YNEY, · (1 (EY,, varyi n For the following population distributions f, write the approximate distribution of the sample mean.
