Transcript text: Form an ordered array, given the following stem-and-leaf display from a sample of $n=7$ midterm exam scores in information systems.
\[
\begin{array}{l}
5 / 2 \\
6 \\
7445 \\
837 \\
98
\end{array}
\]
The ordered array is $\square$
Solution
Solution Steps
Step 1: Understand the Stem-and-Leaf Display
The stem-and-leaf display provided represents the midterm exam scores. Each stem corresponds to the tens digit, and each leaf corresponds to the units digit of the scores. For example:
\(5 / 2\) represents the score 52.
\(6\) represents the score 60.
\(7445\) represents the scores 67, 64, 64, and 65.
\(837\) represents the scores 83 and 87.
\(98\) represents the score 98.
Step 2: Extract All Scores from the Stem-and-Leaf Display
From the stem-and-leaf display, extract all the individual scores:
From \(5 / 2\): 52.
From \(6\): 60.
From \(7445\): 67, 64, 64, 65.
From \(837\): 83, 87.
From \(98\): 98.
Step 3: Form the Ordered Array
Arrange the extracted scores in ascending order:
52, 60, 64, 64, 65, 67, 83, 87, 98.
The ordered array is \(52, 60, 64, 64, 65, 67, 83, 87, 98\).
