Question

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. What is the smallest level of significance at which the null hypothesis will still not be rejected

Answer 1

The smallest level of significance at which the null hypothesis will still not be rejected is 0.05.

Explanation:

The
`p-` value of t-test is
`0.725009`. This
`p-` value is greater than
`0.05`.

Hence, the null hypothesis is not rejected and conclude that there is no sufficient evidence of a difference in the mean amount of time required to reach a customer service representation between two hotels.
