Expert Solution
Step 1

A stem and leaf display is created by first diving each value in the data into stems and leaves. For two-digit data, the first digit(tens) is considered as stem, and the second digit(ones) is considered as the leaf.

To create a stem and leaf display by repeating each stem twice the leaves are divided into two sets. All leaves that are less than equal to 5 in one set and the leaves that are more than 5 in the other set.
