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, suppose α = 0.05. Which of the following represents the correct conclusion for a test on a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels?
A) There is no evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
B) 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.
C) There is no evidence that the variabilities of the amount of time required to reach a customer service representative between the two hotels are the same.
D) There is evidence that the variabilities of the amount of time required to reach a customer service representative between the two hotels are the same.

If the test statistic falls within the acceptance region at α = 0.05, we fail to reject the null hypothesis, indicating no evidence of a difference in variabilities.
