Quizplus · Accepted Answer

The sample in the study refers to the specific group of objects or individuals that are being observed or measured. In this case, the sample is the 250 randomly selected mature Mountain Ash gum trees that are being measured to determine factors that contribute to their height. Therefore, option A is the correct choice for the sample in this study. Option B refers to a specific subset of the trees, and option C includes trees of any age, which is beyond the scope of the study. Option D refers to all the trees in the park, but only a sample of 250 is being studied.
