A consumer group conducts a study to compare the average miles per gallon (mpg) achieved in road tests of two popular car brands. To test the null hypothesis of no difference between µ₁, the true average miles per gallon for Brand 1, and µ₂, the true average miles per gallon for Brand 2, state the null and alternative hypotheses for the hypothesis test.
(1) Ηο: μι 7 μ2; Η: μ₁ = H2
(ii) Ho: μ₁ = μ2; Η: μι≠ με
(iii) Ho: μ₁ = 2; Η: μι < μ₂
(iv) Ho: μ₁ = μ2; Η: μι > μ₂
Exit 33
