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. Click the icon to view the data on roundtrip airline fares. a. At the 0.01 level of significance, is there evidence of a difference in mean roundtrip fare between Airline A and Airline B? Let μ, be the mean roundtrip fares for Airline A, and let μ₂ be the mean roundtrip fares for Airline B. What are the correct null and alternative hypotheses? OA. Ho: HD #0 (where HD =H₁-H₂) B.
