Answer:

The answer is B, 7.83 meters.

Explanation:

The mean of the six trees refers to the average height of all six trees. To find the mean value of any set of values, simply follow this formula:

Mean =
(Sum of all values)/(Number of values you used)

So for this particular question, my working was:

Mean = (5m + 8m + 12m + 6m + 11m + 5m)/6 = 7.833333333333m (Round off to 3 significant figures to get 7.83m)
