To create a stem-and-leaf plot for the dataset {91, 97, 85, 88, 70, 90, 92, 72}, we need to separate the data into stems (the tens) and leaves (the units).

Here's how the data breaks down:

70: Stem is 7, Leaf is 0
72: Stem is 7, Leaf is 2
85: Stem is 8, Leaf is 5
88: Stem is 8, Leaf is 8
90: Stem is 9, Leaf is 0
91: Stem is 9, Leaf is 1
92: Stem is 9, Leaf is 2
97: Stem is 9, Leaf is 7

Now, we can organize the stems and leaves:

Stem 7: Leaves are 0, 2 (which we write as 7 | 02)
Stem 8: Leaves are 5, 8 (which we write as 8 | 58)
Stem 9: Leaves are 0, 1, 2, 7 (which we write as 9 | 0127)

Putting it all together, the stem-and-leaf plot looks like this:

7 | 02
8 | 58
9 | 0127

Now, to answer the specific question about the top row of the stem-and-leaf plot:

The top row of the stem-and-leaf plot is 7 | 02.

Therefore, the correct response is: 7|02 (7 vertical bar 02).
