Solution

The correct option is A 5.8666 feet
Mean = $\frac{S u m o f a l l d a t a p o i n t s}{N u m b e r o f d a t a p o i n t s}$

Thus, to find the mean height of the trees, we need to divide the sum of all heights by the total number of trees.

Thus, the mean height of Abel's trees = $\frac{7 + 5.3 + 4.9 + 8 + 3.8 + 6.2}{6}$ = 5.8666 feet
