Explanation:

A stem and leaf plot is a type of data display that organizes data by showing the distribution of values along an axis. It provides a quick and easy way to see the distribution of the data.

In a stem and leaf plot, each value in the dataset is split into two parts: a stem and a leaf.

• The stems are listed in a column.
• The leaves are listed in a row next to the corresponding stem, in increasing order.

Each data point of the given data set has two-digits. Therefore, the value of the tens digit of each data point is the stem, and the value of the ones digit of each data point is the leaf.

Order the given set of data from smallest to largest:

• 33, 38, 40, 46, 48, 50, 52, 54, 55, 61, 65, 67, 70, 71

The stem value is the tens digit of each data point. Therefore, the stem values are 3, 4, 5, 6, and 7.

Usually we would write the stem values in a column from smallest to largest, but as the given answer options show the stem values from largest to smallest, we will write the stem values in a column from largest to smallest:

`\begin{array}r7&\\6&\\5&\\4&\\3&\end{array}`

The leaf value is the ones digit of each data point.

Write the leaf values in a row next to each stem value in increasing order.

For example, the numbers 70 and 71 both have 7 as their stem value. Their leaf values are 0 and 1, so write these in increasing order in the row next to the 7.

Therefore, the completed stem and leaf plot for the given data is:

`\begin{array}r7&0&1&&\\6&1&5&7&\\5&0&2&4&5\\4&0&6&8&\\3&3&8&&\end{array}`
