D. Test if two species of plants are found together because they are associated and contribute to ecological factors which enhance the growth of both plants.
参考答案: D
本题详细解析:
Explanation: The data collected for recording the presence and absence of two plants can be used in a chi-squared test to determine if the two plants are associated. This is a relevant statistical method. The biodiversity found in an area (Choice A) is usually determined by using Simpson’s Diversity Index or other similar calculations. The chi-squared test cannot be used to find the range (Choice B) for heights of trees or predict the probability of finding certain plants (Choice C) in an area.
