question 57

Multiple Choice

TABLE 10-14
The amount of time required to reach a customer service representative has a huge impact on customer satisfaction. Below is the Excel output from a study to see whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels. Assume that the population variances in the amount of time for the two hotels are not equal.

-Referring to Table 10-14, which of the following represents the relevant hypotheses tested?

• A) H₀ : μ_I - μ_II ≥ 0 versus H₁ : μ_I - μ_II < 0
• B) H₀ : μ_I - μ_II ≤ 0 versus H₁ : μ_I - μ_II > 0
• C) H₀ : μ_I - μ_II = 0 versus H₁ : μ_I - μ_II ≠ 0
• D) H₀ : μ_I - μ_II ≠ 0 versus H₁ : μ_I - μ_II = 0
