question 219

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, state the null and alternative hypotheses for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.

• A) H₀: σ₁² - σ₂² ≥ 0 versus H₁: σ₁² - σ₂² < 0
• B) H₀: σ₁² - σ₂² ≤ 0 versus H₁: σ₁² - σ₂² > 0
• C) H₀: σ₁² - σ₂² = 0 versus H₁: σ₁² - σ₂² ≠ 0
• D) H₀: σ₁² - σ₂² ≠ 0 versus H₁: σ₁² - σ₂² = 0
