How many minutes does the average patient at the UK emergency room wait before being seen...
How many minutes does the average patient at the UK emergency room wait before being seen by a physician? UK medical center states that the average waiting time in their emergency room is 45 minutes. You track 40 patients who enter the emergency room and find an average waiting time of 67.3 minutes with a variance of 34.1 minutes. What statistical test should be used to determine if UK claims are incorrect?

The amount of time that you have to wait before seeing the doctor in the doctor's office is normally distributed with a mean of 15.2 minutes and a standard deviation of 15.2 minutes. If you take a random sample of 64 patients, what is the probability that the average wait time is greater than 20 minutes?
