Travel and Transportation Since airlines began charging for checked luggage, more passengers use carry-on bags to avoid the extra fee. For those who check luggage, the wait at the baggage carousel while jostling with other passengers can be long and infuriating. A study was conducted to determine whether there is a relationship between the flight time (x, in hours) and the amount of time for a bag to arrive from a plane to the carousel (y, in minutes). A random sample of arriving flights at the Denver International Airport was obtained and the flight time and baggage time were recorded for each.

a. Construct a scatter plot for these data. Describe the relationship between flight time and the amount of time for a bag to arrive from a plane to the carousel.

b. Find the estimate regression line, complete the ANOVA table, and conduct an F test for a significant regression. Use a = 0.05.

c. Based on your results in part (b), does flight time affect the time it takes for a bag to arrive at the carousel? What are some other variables that might affect this time?
