The wait times to see a doctor at a large clinic are normally distributed with a mean of 68.2 minutes and a standard deviation of 14.8 minutes. Find the probability that the waiting time to see a doctor is less than 45.0 mintues. Round to four decimal places.

The office manager of a doctor's office wants to evaluate how long patients are waiting in the waiting room for their appointment. They find that the mean wait time is 17.2 minutes and the standard deviation is 7.3 minutes. If the office manager takes a random sample of 40 patients, what is the probability that their mean wait time will be more than 15 minutes?

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 $1.5 \mathrm{hr}$, with a sample standard deviation of $0.5 \mathrm{hr}$. Explain in complete sentences what the confidence interval means.
