The Transportation Security Administration would like to compare the average amount of time it takes passengers to pass through airport security at Philadelphia versus Orlando during peak times. A random sample of 25 travelers in Philadelphia spent an average of 14.6 minutes to pass through airport security with a sample standard deviation of 5.8 minutes. A random sample of 27 travelers in Orlando spent an average of 11.5 minutes to pass through airport security with a sample standard deviation of 4.9 minutes.
a. Perform a hypothesis test using α = 0.05 to determine if the average time to pass through security in Philadelphia is more than the average time to pass through security in Orlando.









b. Approximate the p-value for this hypotheses and interpret the results.







c. What assumptions need to be made in order to perform this procedure?

Southwest Airlines (SWA) is evaluating the customer check-in and security process for its operations at Albany International Airport (ALB) in Albany, New York. ALB is a relatively small airport, serving approximately 1.4 million (1,400,000) passengers per year. Southwest is the largest carrier at ALB, accounting for about 40% of the overall passenger volume. ALB does not accept mobile boarding passes, so all customers must retrieve their boarding passes at the airport (assume print-at-home is not an option). When Southwest passengers...
