Let
Hss, µms, HLs, Hsuy and μMy represent the mean costs per mile for small sedans, medium sedans, large sedans, SUV 4WDs, and minivans
respectively. What are the hypotheses for this test?
A. Ho: Hss HMS HLS="SUV HMV
H₂: Not all the means are equal.
=
B. Ho: Hss HMS = μLS="SUV = HMV
Ha: Hss #HMS # μLS *μSUV HMV
OC. Ho: Not all the means are equal.
Ha: Hss
