A hospital is trying to cut down on emergency room wait times. It is interested in the amount of time patients must wait before being called back to be examined. An investigation committee randomly surveyed 70 patients. The sample mean was 1.5 hours with a sample standard deviation of 0.5 hours. Explain in complete sentences what the 95% confidence interval for the population mean time spent waiting means. There is a 95% chance that a patient's wait time lies within this interval. We are 95% confident that the true population mean time of all patient wait times lies within this interval. We are 95% confident that the mean time of the sample of 70 patients wait time lies within this interval. We are 95% confident that a patient's wait time lies within this interval.
