Answer:
9.2yrs
Step-by-step explanation:
Given data:
Ages of trees in the school property:
3 years, 8 years, 10 years, 14 years, 11 years
The problem here is finding the mean age of these trees.
The mean is the average of a given data set. It is the sum of all the data given divided by the number of the data.
Mean = [tex]\frac{Total number of data}{number of data given}[/tex] = [tex]\frac{3 + 8 + 10 + 14 + 11}{5}[/tex] = 9.2yrs
