The amount of time required to reach a customer service representative
has a huge impact on customer satisfaction. Below is the Excel output
for significance level 0.05 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.
