Problem
Use a stern-and-leaf plot to display the data, which represent the thickness (in centimeters) of ice measured at 20 different iocatans on a frozen lake Desaite ifil patterns. \begin{tabular}{lllllllllll} 5.8 & 6.3 & 6.9 & 7.2 & 5.1 & 4.9 & 4.9 & 5.8 & 7.0 & 6.8 & 0 \\ 8.7 & 7.5 & 7.2 & 5.1 & 7.2 & 8.0 & 7.3 & 6.9 & 5.9 & 5.9 \end{tabular} Determine the leaves in the stem-and-leaf plot below. Key: $3 / 3=3.3$
Solution
Step 1 ：Sort the given data in ascending order.
Step 2 ：Separate the data into stems and leaves. The stem will be the integer part of the number and the leaf will be the decimal part of the number.
Step 3 ：Organize the stems and leaves into a stem-and-leaf plot.
Step 4 ：\(\text{Final Answer: The leaves in the stem-and-leaf plot are }\boxed{0, 9, 9, 1, 1, 8, 8, 9, 9, 3, 8, 9, 9, 0, 2, 2, 2, 3, 5, 0, 7}\)
