TABLE 10-13 The Amount of Time Required to Reach a Customer Service

question 235

Multiple Choice

TABLE 10-13
The amount of time required to reach a customer service representative has a huge impact on customer satisfaction. Below is the Microsoft 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 10-13, which of the following represents the relevant hypotheses to test whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels?

• A) H₀: π₁ - π₂ ≥ 0 versus H₁: π₁ - π₂ < 0
• B) H₀: π₁ - π₂ ≤ 0 versus H₁: π₁ - π₂ > 0
• C) H₀: π₁ - π₂ = 0 versus H₁: π₁ - π₂ ≠ 0
• D) H₀: π₁ - π₂ ≠ 0 versus H₁: πI - π₂ = 0
