do the math

8:30 to 5:00. That’s the window of time I was given by my office supply store to wait for the delivery of my new file cabinets.

Um, can you narrow that down a bit? If you could just give me a probability curve of delivery times based on where I fall in the order of deliveries, that would be swell. A simple bell curve would be fine.

Is that asking too much? I don’t think so.
