Question

The figure below shows a histogram of heights of cherry trees. Find the correct statement(s) among the options.

• A. Total number of trees is 31
• B. The most common range of height of trees is 70-75 feet
• C. Least common range of height is 85-90 feet
• D. Total number of trees is 32

Answer 1

Answer: (A), (C)

Least common range of height is 85-90 feet

If we add the frequencies of all the bars, total number of trees=3+3+8+10+5+2=31


The highest bar belongs to the range of 75-80 feet. So, the most common range of height is 75-80 feet.

The shortest bar belongs to the range of 85-90 feet. So, the least common range of height is 85-90 feet.
