Restaurant wait time question?
My roommate's stats prof asked his class a question and offered $10 to anyone who can come up with the correct answer by next class. I'm not sure if there is a correct answer, so I thought I'd post it here to get your opinion.
When you get to a restaurant, the hostess tells you that the median wait time is 15 minutes. After 5 minutes, what will be your average wait time?
That's all the information we were given. To me, it seems as though there cannot be a single correct answer because you cannot directly relate the median and the mean. It seems to me that you would need to make additional assumptions. Am I missing something here?
