The lengths of $62$ leaves of a plant are measured in millimetres and the data is represented in the following table:

Length (in mm)	Number of leaves
$118-126$	$8$
$127-135$	$10$
$136-144$	$12$
$145-153$	$17$
$154-162$	$7$
$163-171$	$5$
$172-180$	$3$

Draw a histogram to represent the data above.

(N/A) The given table is in inclusive form. To draw a histogram,we must first convert it into an exclusive form by finding the difference between the upper limit of one class and the lower limit of the next class. Here,the difference is $127 - 126 = 1$. We subtract $0.5$ from each lower limit and add $0.5$ to each upper limit.

Length (in mm)	Number of leaves
$117.5-126.5$	$8$
$126.5-135.5$	$10$
$135.5-144.5$	$12$
$144.5-153.5$	$17$
$153.5-162.5$	$7$
$162.5-171.5$	$5$
$171.5-180.5$	$3$
