Multiple Choice

SCENARIO 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. $$\begin{array}{l}\text { t-Test: Two-Sample Assuming Unequal Variances }\\\begin{array} { l r r } \hline & \text { Hotel 1 } & \text { Hotel 2 } \\\hline \text { Mean } & 2.214 & 2.0115 \\\text { Variance } & 2.951657 & 3.57855 \\\text { Observations } & 20 & 20 \\\text { Hypothesized Mean Difference } & 0 & \\\text { df } & 38 & \\\text { t Stat } & 0.354386 & \\\text { P } ( T < = t ) \text { one-tail } & 0.362504 & \\\text { t Critical one-tail } & 1.685953 & \\\text { P } ( \text { T } < \text { t) two-tail } & 0.725009 & \\\text { t Critical two-tail } & 2.024394 & \\\hline\end{array}\end{array}$$
-Referring to Scenario 10-13, suppose $\alpha$ = 0.05.Which of the following represents the result of the test on a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels?

A) The alternative hypothesis is rejected.
B) The null hypothesis is rejected.
C) The null hypothesis is not rejected.
D) Insufficient information exists on which to decide.
