Given below is a frequency distribution table. Read it and answer the questions that follow:

Which interval has a frequency of $10$?

Given below is a frequency distribution table. Read it and answer the questions that follow:

Which interval has the lowest frequency?

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

Which class interval has the least number of students?

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

Construct a frequency distribution table for the following weights (in grams) of 35 mangoes, using the equal class intervals, one of them is $40-45$ ($45$ not included).
$30, 40, 45, 32, 43, 50, 55, 62, 70, 70, 61, 62, 53, 52, 50, 42, 35, 37, 53, 55, 65, 70, 73, 74, 45, 46, 58, 59, 60, 62, 174, 34, 35, 70, 68$

Which weight group has the highest frequency?

The below histogram shows the number of literate females in the age group of $10$ to $40$ years in a town.

In which age group are Iiterate females the least?

The below histogram shows the number of literate females in the age group of $10$ to $40$ years in a town.
