Look at the histogram below and answer the questions that follow.

How many students have height less than $140 \mathrm{cm}$?

Following are the number of members in $25$ families of a village:
$6, 8, 7, 7, 6, 5, 3, 2, 5, 6, 8, 7, 7, 4, 3, 6, 6, 6, 7, 5, 4, 3, 3, 2, 5$.

Prepare a frequency distribution table for the data using class intervals $0-2, 2-4$ etc.

Following are the number of members in $25$ families of a village:
$6, 8, 7, 7, 6, 5, 3, 2, 5, 6, 8, 7, 7, 4, 3, 6, 6, 6, 7, 5, 4, 3, 3, 2, 5$.

Prepare a frequency distribution table for the data using class intervals $0-2, 2-4$ etc.

The marks obtained (out of $20$ ) by $30$ students of a class in a test are as follows:
$14, 16, 15, 11, 15, 14, 13, 16, 8, 10, 7, 11, 18, 15, 14, 19, 20, 7, 10, 13, 12, 14, 15, 13, 16, 17, 14, 11, 10, 20$.
Prepare a frequency distribution table for the above data using class Intervals of equal width in which one class interval is $4-8$ (excluding
$8$ and including $4$).

Prepare a histogram from the frequency distribution table obtained.

The weights (in $\mathrm{kg}$) of $30$ students of a class are:
$39, 38, 36, 38, 40, 42, 43, 44, 33, 33, 31, 45, 46, 38, 37, 31, 30, 39, 41, 41, 46, 36, 35, 34, 39, 43, 32, 37, 29, 26$.
Prepare a frequency distribution table using one class interval as $(30-35 ), 35$ not included.

Which class has the least frequency?

The weights (in $\mathrm{kg}$) of $30$ students of a class are:
$39, 38, 36, 38, 40, 42, 43, 44, 33, 33, 31, 45, 46, 38, 37, 31, 30, 39, 41, 41, 46, 36, 35, 34, 39, 43, 32, 37, 29, 26$.
When a frequency distribution table using class intervals like $(30-35 ), 35$ not included is prepared, then the class which has the maximum frequency is
