The owners of a restaurant determine that the number of minutes that a customer waits to be served is normally
distributed with a mean of 6 minutes and a standard deviation
of 2 minutes.
13. What is the probability that a randomly selected customer will be
served in less than 4 minutes?
14. During a survey, 500 customers are served. How many would you
expect to be served in less than 8 minutes?
15. If too customers are served, how many would you expect to
wait between 4 minutes and 10 minutes?
