So we'll put 12 right over here. Let's try out another one. A statistician for a chain of department stores created the following stem and leaf plot showing the number of watches at each of the stores. How many department stores have exactly seven watches? Well, that's only this one right over here, zero, seven, watches, this one right, this, this, and that one are not seven. This is representing 17 because it's in the row with one at the beginning. This right over here represents 27 because it's in the row with the two at the beginning.
