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

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 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 tested?

A) H₀: μI - μII ≥ 0 versus H₁: μI - μII < 0
B) H₀: μI - μII ≤ 0 versus H₁: μI - μII > 0
C) H₀: μI - μII = 0 versus H₁: μI - μII ≠ 0
D) H₀: μI - μII ≠ 0 versus H₁: μI - μII = 0
