How do the fares for airlines that directly compete compare? The accompanying table contains roundtrip fares for nonstop travel from a particular city to 10 different destinations in the same country on two airlines that a frequent flyer collected. Complete parts (a) through (c) below. E Click the icon to view the data on roundtrip airline fares. What is the correct conclusion at the 0.10 level of significance? O A. Reject Ho. There is sufficient evidence to conclude that there is a difference between the mean roundtrip fares between Airline A and Airline B. O B. Do not reject Hg. There is sufficient evidence to conclude that there is a difference between the mean roundtrip fares between Airline A and Airline B. OC. Reject Ho. There is insufficient evidence to conclude that there is a difference between the mean roundtrip fares between Airline A and Airline B. OD. Do not reject Hg. There is insufficient evidence to conclude that there is a difference between the mean roundtrip fares between Airline A and Airline B. b. What assumption is necessary in order to perform the test? O A. The distribution of the differences between the fares is approximately uniform. O B. The distribution of the differences between the fares is skewed. Oc. The distribution of the differences between the fares is approximately binomial. OD. The distribution of the differences between the fares is approximately normal. c.
