The amount of time required to reach customer service representatives has a huge impact on customer satisfaction. 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 is provided. Assume that the population variances in the amount of time for the two hotels are not equal. What assumptions are necessary for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer representative between the two hotels to be valid?

A. Both sampled populations are normally distributed.

B. Both samples are random and independent.

C. Neither A nor B is necessary.

D. Both A and B are necessary.
