Answer 1

Answer: (A), (C)

The correct options are
A

Total number of trees is 31

C

Number of trees in the height range 60 - 65 is 3

If we add the frequencies of all the graphs, total number of trees=3+3+8+10+5+2=31
Hence, option A is correct and D is incorrect.
The highest bar belongs to the range of 75-80 feet.
So, option B is incorrect.
Number of trees in the height range 60 - 65 is 3
So, option C is correct.
