Question

How many students have heights less than $180$ cm?

• A. $40$
• B. $63$
• C. $38$
• D. $53$

Answer 1

Answer: (C)

$38$

From the histogram, the frequency associated with the class width is as follows:

$120-140$ is $4$

$140-160$ is $10$

$160-180$ is $24$

$180-200$ is $10$

$200-220$ is $15$

$220-240$ is $7$.

Therefore, number of students who have heights less than $180$ cm $=24+10+4=38$.

Hence, option $C$ is correct.
