Explanation:

Step1: Sort the data

First, we sort the given data set: \(38, 38, 41, 50, 50, 52, 53, 53, 56, 58, 59, 66, 68, 69, 69, 70, 70, 73, 74, 75, 78, 80, 81, 83, 83, 89, 89, 90, 91, 92\)

Step2: Determine stems and leaves

The stems are the tens - digit of the numbers. For example, for the number \(38\), the stem is \(3\) and the leaf is \(8\).

• Stem \(3\): leaves \(8,8\)
• Stem \(4\): leaf \(1\)
• Stem \(5\): leaves \(0,0,2,3,3,6,8,9\)
• Stem \(6\): leaves \(6,8,9,9\)
• Stem \(7\): leaves \(0,0,3,4,5,8\)
• Stem \(8\): leaves \(0,1,3,3,9,9\)
• Stem \(9\): leaves \(0,1,2\)

Answer:

Stems	Leaves
4	1
5	0,0,2,3,3,6,8,9
6	6,8,9,9
7	0,0,3,4,5,8
8	0,1,3,3,9,9
9	0,1,2
