Suppose the amount of time a doctor spends with their patients is normally distributed with a mean of 17.4 minutes and with standard deviation of 3.8 minutes. Suppose 26 patients have scheduled appointments on one day. What is the probability that the mean amount of time for those 26 patients is less than 18.5 minutes, which would be equivalent to the doctor seeing patients for 8 hours and 1 minute that day.

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. If a simple random sample of 25 patients is selected, find the probability that the sample mean wait time is more than 75 minutes. Round to four decimal places.

A doctor has scheduled an appointment for patient A at 2:00 p.m. and an appointment for patient B at 2:40 p.m. The amounts of time that the appointments last are independent, identically distributed, exponential random variables with mean 40 minutes. Assuming that both patients arrive exactly on time, (a) Calculate the probability that patient A will still be in the doctor’s office at 2:45 p.m. (b) Find the expected amount of time that patient B spends at the doctor’s office.
