Question 2 (Multiple Choice Worth 2 points)

In the 2021 football season, the Riverside Red Dragon's manager gathered the points scored by the team during the regular season games. The following data set shows the values collected by the manager.
[tex]\{17, 0, 28, 17, 17, 20, 28, 11, 17, 22, 24, 33, 20, 31, 20, 3\}[/tex]

Which of the following stem-and-leaf plots correctly graphs the data set?

\begin{tabular}{l|l}
\multicolumn{2}{l}{Season Points} \\
\hline
0 & 03 \\
1 & 17777 \\
2 & 0002488 \\
3 & 13 \\
\end{tabular}

Key: [tex]1 \mid 1 = 11[/tex]



Answer :

To correctly graph the given data set [tex]\(\{17, 0, 28, 17, 17, 20, 28, 11, 17, 22, 24, 33, 20, 31, 20, 3\}\)[/tex] into a stem-and-leaf plot, we need to organize the numbers by their tens (stems) and units (leaves). Here's how you can do it:

1. Split each number into its stem and leaf:
- 0 -> Stem: 0, Leaf: 0
- 3 -> Stem: 0, Leaf: 3
- 11 -> Stem: 1, Leaf: 1
- 17 -> Stem: 1, Leaf: 7
- 17 -> Stem: 1, Leaf: 7
- 17 -> Stem: 1, Leaf: 7
- 17 -> Stem: 1, Leaf: 7
- 20 -> Stem: 2, Leaf: 0
- 20 -> Stem: 2, Leaf: 0
- 20 -> Stem: 2, Leaf: 0
- 22 -> Stem: 2, Leaf: 2
- 24 -> Stem: 2, Leaf: 4
- 28 -> Stem: 2, Leaf: 8
- 28 -> Stem: 2, Leaf: 8
- 31 -> Stem: 3, Leaf: 1
- 33 -> Stem: 3, Leaf: 3

2. Organize the data into stems and their corresponding leaves:
- For stem 0, the leaves are [0, 3].
- For stem 1, the leaves are [1, 7, 7, 7, 7].
- For stem 2, the leaves are [0, 0, 0, 2, 4, 8, 8].
- For stem 3, the leaves are [1, 3].

3. Construct the stem-and-leaf plot in a tabular format:
[tex]\[ \begin{array}{l|l} \multicolumn{2}{l}{\text{2021 Riverside Red Dragon Football Season Points}} \\ \hline 0 & 03 \\ 1 & 17777 \\ 2 & 0002488 \\ 3 & 13 \\ \end{array} \][/tex]

This stem-and-leaf plot correctly represents the given data set. Here's why:

- Stem 0: Leaves are 0, 3 => 03
- Stem 1: Leaves are 1, 7, 7, 7, 7 => 17777
- Stem 2: Leaves are 0, 0, 0, 2, 4, 8, 8 => 0002488
- Stem 3: Leaves are 1, 3 => 13

Thus, the correct stem-and-leaf plot for the provided data set is:
[tex]\[ \begin{tabular}{l|l} \multicolumn{2}{l}{Season Points} \\ \hline 0 & 03 \\ 1 & 17777 \\ 2 & 0002488 \\ 3 & 13 \\ \end{tabular} \][/tex]
