Explanation:

Step1: Understand stem - plot

In a stem - plot, the left - hand column is the stem and the right - hand values are the leaves. Each data value is formed by combining the stem and the leaf. For example, for the row with stem 5 and leaves 0, 1, 1, 3, 6, the data values are 50, 51, 51, 53, 56. For the row with stem 6 and leaves 2, 9, the data values are 62, 69. For the row with stem 7 and leaves 1, 1, 3, 5, 7, the data values are 71, 71, 73, 75, 77.

Step2: Check options

• Option A: 29 inches is not in the data set as there is no stem of 2 in the given stem - plot.
• Option B: 72 inches is not in the data set as the leaves for stem 7 are 1, 1, 3, 5, 7.
• Option C: 57 inches is not in the data set as the leaves for stem 5 are 0, 1, 1, 3, 6.
• Option D: 50 inches is in the data set as it corresponds to the stem 5 and leaf 0.

Answer:

D. 50 inches
