Statistics Problem: Sampling Distributions - Somewhat OT

  1. Oct 16, 2004 #1
    You are on the staff at the Post Office. Your job is to find a process to find the average waiting time for service. How do you collect the data, and once it is collected, what do you do next?

    what? Average waiting time would equal the amount of time a customer waited. You'd have to pick a certain amount to be constant-- such as how many customers' wait time you are counting. By collecting the data, how would you find out their wait time? i.e., they take a ticket when they get there with the time stamped on it, and when there number s called, wait time end. after that, you add it all up and divide by the number of customers who's wait time was included.
