The weights (in kg) of 30 students of a class are
39, 43, 32, 37, 29, 26, 31, 45, 46, 31, 37, 38, 30, 39, 36, 41, 35, 34, 41, 46, 39, 38, 36, 38, 40, 42, 33, 43, 44, 33.
Prepare a frequency distribution table using one class interval as 30–35, in which 30 is included and 35 excluded. Using the above data. draw a histogram.

Answer 1

Frequency distriubution table

Weight(in kg)	Tally Marks	Number of students
25-30	$\left|\right|$	2
30-35	$\cancel{\left|\right|\left|\right|}$ $\left|\right|$	7
35-40	$\cancel{\left|\right|\left|\right|}$ $\cancel{\left|\right|\left|\right|}$ $|$	11
40-45	$\cancel{\left|\right|\left|\right|}$ $\left|\right|$	7
45-50	$\left|\right||$	3
Total =		30
