The pulse rates, in beats per minute, of a random sample of 15 small animals are shown in the following table.
115, 120, 158, 132, 125, 104, 142, 160, 145, 104, 162, 117, 109, 124, 134
Draw a stem-and-leaf diagram to represent the data.
To create a stem-and-leaf diagram, we first identify the stems and leaves from the data set. The stems are the tens digits, and the leaves are the units digits.
1. List the stems: 10, 11, 12, 13, 14, 15, 16.
2. Assign the leaves to each stem:
Key: \( 10 \mid 4 \) represents \( 104 \).
