Suppose that juan is reviewing the responses to customer interviews conducted by the software company he works for. he notices that some customers are very impressed with the support that they get from the technical assistance hotline, but others are highly unsatisfied. he wonders whether the length of time these customers spent on hold affected their responses. juan uses a random number generator to select call identification numbers for a sample of five calls placed by customers who expressed satisfaction with the technical assistance hotline. he finds that these customers had a mean wait time of 1.34 min with a standard deviation of 1.02 min. juan also selects a sample of five customers who were unsatisfied with the technical assistance hotline. these customers waited an average of 2.54 min with a standard deviation of 2.01 min. juan plans to use this information to construct a two-sample ‑confidence interval for the difference between these two means. have the requirements for such a confidence interval been met? if any requirement has not been met, leave the boxes below that requirement unanswered.
