Tasks:
a. Make a stem-and-leaf display for the first-round scores. Use two lines per stem as explained in the 2.3 notes.

b. Make a stem-and-leaf display for the fourth-round scores. Use two lines per stem as explained in the 2.3 notes.

c. Describe how the overall shapes of the two plots differ.

The stem-and-leaf displays for the first and fourth round scores of the U.S. Open Golf Tournament depict the distribution of player scores. The displays show a difference in player scoring patterns, with the fourth round indicating improved golf performance.

Explanation:

First-Round Stem-and-Leaf Display

Title: First Round Scores at U.S. Open Golf Tournament

Key: 6 | 5 = 65

6 | 5 6 7 7
6 |
7 | 0 1 1 1 1 1 1 1 1 1
7 | 2 2 3 3 3 3 4 4 4 4 5 5 5 5 5
7 | 5

Fourth-Round Stem-and-Leaf Display

Title: Fourth Round Scores at U.S. Open Golf Tournament

Key: 6 | 8 = 68

6 | 8 9 9 9 9 9
6 |
7 | 0 0 0 1 1 1 1 1 1 1 1
7 | 2 2 2 2 2 2 3 3 3 3 3 3 4 4 4
7 |

Comparison of the Plots

The overall shapes of the two stem-and-leaf displays show differences in distribution of scores. The first-round display has a concentration in the lower 70s range, with a relatively even spread of scores from 65 to 75.

In contrast, the fourth-round display shows a tighter clustering of scores around the par score of 70, with fewer high scores, indicating improved performance over the course of the tournament.
