Answer :

Final answer:

The median height of the group of plants, when the plant heights are arranged in ascending order, is 35.9cm. The correct answer is option c).

Explanation:

To find the median height of the group of plants, we must first arrange the plant heights in ascending order: 30.1cm, 31.6cm, 35.9cm, 43cm, and 45.2cm.

The median is the middle number, which in this case is the third number because there are five measurements. Therefore, the median height of this group of plants is 35.9cm.
