a. At the 0.10 level of significance, is there evidence of a difference in mean roundtrip fare between Airline A and Airline
B?
Let μ₁ 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?
A. Ho: HD 0 (where μD = μ₁ −μ₂)
B. Ho: HD >0 (where μD = μ₁ −μ₂)
H₁: HD ≤0
H₁: HD #0
≥0 (where μD = μ₁ −μ₂)
Ho: HD
H₁ HD <0
Ho: HD <0 (where μ = μ₁ −μ₂)
H₁: HD 20
E. Ho: HD #0 (where μD = μ₁ −μ₂)
F. Ho: HD ≤0 (where μD = μ₁ −μ₂)
H₁: HD
= 0
H₁: HD > 0
What is the test statistic?
