Answer

Explanation:

Step1: Organize data for stemplot

First, we consider the tens - digit as the stem and the units - digit as the leaf.

Step2: Construct stemplot

6 | 0 2 4 6 6 6 8 7 | 0 0 0 0 2 2 2 4 6 6 6 6 8 8 | 4 8 9 | 0 4 6

Step3: Find the median - related values

There are 25 data points. When the data is sorted, the 12th and 13th values are used to find the median. Sorting the data: 60, 62, 64, 66, 66, 66, 68, 70, 70, 70, 70, 72, 72, 72, 74, 76, 76, 76, 76, 78, 84, 88, 90, 94, 96. The 12th value is 72 and the 13th value is 72.

Answer:

Stemplot: 6 | 0 2 4 6 6 6 8 7 | 0 0 0 0 2 2 2 4 6 6 6 6 8 8 | 4 8 9 | 0 4 6 Values closest to the middle: 72, 72
