A student randomly selected 20 novels from the local library and recorded the number of pages in each of the novels. The data are as follows: 225, 252, 191, 218, 246, 259, 204, 216, 219, 247, 207, 279, 241, 224, 216, 225, 222, 218, and 220. To make a stemplot, what should the stems be?

• 9, 1, 2, 3, 4, 5, 6, 7

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

• 19, 20, 21, 22, 23, 24, 25, 26, 27

• This data cannot be displayed using a stemplot.
