Final answer:
To create a stem-and-leaf display for the first-round scores, separate the stems and leaves of the scores and group them accordingly. The display shows the range of scores and the most common score.
Explanation:
To create a stem-and-leaf display for the first-round scores, we need to separate the stems and leaves. The stems are the tens digit of each score, while the leaves are the units digit. Grouping the scores by their stems, we can create the display:
6 | 6
7 | 0 0 1 1 1 1 1 1 1 2 2 2 4 5 5 5
8 | NONE
From this display, we can see that the scores range from 66 to 75, with the most common score being 71. There are no scores in the 80s.
