Answer:
d) selection-maturation effect.
Explanation:
Based on the scenario being described within the question it can be said that this could also equally reflect the selection-maturation effect. This term refers to a differential rate of normal growth that occurs between pre-test and pos-tests. Such as is the case in this scenario since the scores have increased drastically between these two stages of the testing period.

Answer:
10 trees per hectare
Explanation:
It is given that the density of Douglas firs is estimated by counting them in four sample plots of each one hector.
And the number of trees in each hector of the forest lands are --- 10, 12, 7, and 11, respectively.
Therefore in order to find the estimated number of tress or density of Douglas firs in the forest by taking the average number of tress in these four hectors. This will give us an estimated density of Douglas firs across the forest.
Therefore, (10 + 12 + 7 + 11) / 4 = 40 / 4
= 10
Therefore there are 10 Douglas fir trees in each hector.
Thus the answer is --
10 trees per hectare
