In the given data, there are 17 data points. To divide them into three groups for the median-median line, we need to have approximately equal numbers of points in each group.
Since 17 is not easily divisible by 3, we need to have different numbers of data points in each group. The closest distribution would be:
Left group: 6 data points
Center group: 5 data points
Right group: 6 data points
Therefore, the correct answer is:
left: 6, center: 5, right: 6
