Customers at the bank have complained about the long wait times. To test whether the average wait time at the bank is greater than 3 minutes, 60 customers were randomly selected as they entered the bank and their wait times were recorded. The mean wait time was 4.7 minutes. A one-sample t-test resulted in a p-value of 0.00031. Which of the following is an appropriate interpretation of the p-value? The probability that the population mean wait time is greater than 3 A minutes is 0.00031. The probability that the sample mean wait time is greater than 3 minutes is В 0.00031. If the population mean wait time is greater than 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.
