Quizplus · Accepted Answer

The population from which the study was sampled is the entire group of adult American pine trees in Yosemite National Forest, which is estimated to be 25,000. The sampling method involved randomly selecting 250 trees from this population to analyze their heights and determine what factors make them grow taller than 60 feet. Option A only represents the sample size, not the entire population. Option C only includes a specific subset of the population based on height. Option D includes all American pine trees in the forest, regardless of whether they are adults or not, which may not be relevant to the study's objectives.
