Question

A commuter has two different routes available to drive to work.She wants to test whether route A is faster than route B.The best hypotheses are: A)H₀ : μ_A - μ_β ≥ 0 H_A : μ_A - μ_β < 0 B)H₀ : μ_A - μ_β ≤ 0 H_A : μ_A - μ_β > 0 C)H₀ : μ_A - μ_β = 0 H_A : μ_A - μ_β ≠ 0 D)H₀ : μ_A - μ_β < 0

The null hypothesis (H0) should state that route A is not faster than route B (i.e., the time for route A is greater than or equal to route B), while the alternative hypothesis (HA) should state that route A is faster (i.e., the time for route A is less than route B).
