The following stem and leaf plot shows the number of students at the local recreational center each day at 4 PM.

\begin{tabular}{c|l}
Stem & Leaf \\
\hline
1 & 6 \\
2 & 225666 \\
3 & 459 \\
4 & 22 \\
5 & 0 \\
6 & \\
7 & 2 \\
\end{tabular}

Which data set is represented by this plot?

Select one:
a. [tex]$16,22,22,24,24,27,34,35,39,42,50,72$[/tex]
b. [tex]$0,2,2,2,2,2,4,5,5,6,6,6,6,9$[/tex]
c. [tex]$16,22,25,26,34,35,39,42,50,72$[/tex]
d. [tex]$16,22,22,25,26,26,26,34,35,39,42,42,50,72$[/tex]



Answer :

To analyze the given stem and leaf plot and translate it into the corresponding data set, follow these steps:

The stem and leaf plot is a way of displaying data in which each data value is split into a "stem" (the first part) and a "leaf" (the last part). Here's the provided plot:

[tex]\[ \begin{tabular}{c|l} Stem & Leaf \\ \hline 1 & 6 \\ 2 & 225666 \\ 3 & 459 \\ 4 & 22 \\ 5 & 0 \\ 6 & \\ 7 & 2 \\ \end{tabular} \][/tex]

We interpret this as follows:

1. Stem = 1, Leaf = 6: The data value is 16.
2. Stem = 2, Leaf = 2, 2, 5, 6, 6, 6: The data values are 22, 22, 25, 26, 26, 26.
3. Stem = 3, Leaf = 4, 5, 9: The data values are 34, 35, 39.
4. Stem = 4, Leaf = 2, 2: The data values are 42, 42.
5. Stem = 5, Leaf = 0: The data value is 50.
6. Stem = 6, Leaf = (none): There are no data values with a stem of 6.
7. Stem = 7, Leaf = 2: The data value is 72.

Now, we compile the data values we have interpreted from the plot into a list:

[tex]\[ [16, 22, 22, 25, 26, 26, 26, 34, 35, 39, 42, 42, 50, 72] \][/tex]

By comparing this interpretation with the given options, the correct data set represented by the stem and leaf plot is:

d. [tex]\(16, 22, 22, 25, 26, 26, 26, 34, 35, 39, 42, 42, 50, 72\)[/tex]
