1. Change the bin width from 10 to 15 and press Enter on your keyboard. How would you describe the shape of this distribution? What what you consider a typical wait time?
2. Change the bin with to 10 (either by entering the value or by using the slider). How would you describe the shape of this distribution? What what you consider a typical wait time?
3. Change the bin with to 5 (either by entering the value or by using the slider). How would you describe the shape of this distribution? What what you consider a typical wait time?

Moral: It's important to choose a bin width that is not too large as that could hide some important features of the distribution. Although a bin width that's too small could make it harder to see the overall pattern.
