# The number of books in different shelves of a library are as follows:30, 32, 28, 24, 20, 25, 38, 37, 40, 45, 16, 20, 19, 24, 27, 30, 32, 34, 35, 42, 27, 28, 19, 34,38, 39, 42, 29, 24, 27, 22, 29, 31, 19, 27, 25, 28, 23, 24, 32, 34, 18, 27, 25, 37, 31, 24, 23,43, 32, 28, 31, 24, 23, 26, 36, 32, 29, 28, 21.Prepare a cumulative frequency distribution table using 45-49 as the last class interval.

Given:

The number of books in different shelves of a library are as follows:

30, 32, 28, 24, 20, 25, 38, 37, 40, 45, 16, 20, 19, 24, 27, 30, 32, 34, 35, 42, 27, 28, 19, 34,

38, 39, 42, 29, 24, 27, 22, 29, 31, 19, 27, 25, 28, 23, 24, 32, 34, 18, 27, 25, 37, 31, 24, 23,

43, 32, 28, 31, 24, 23, 26, 36, 32, 29, 28, 21.

To do:

We have to prepare a cumulative frequency distribution table using 45-49 as the last class interval.

Solution:

Greatest number $= 45$

Lowest number $=16$

Range $= 45 - 16$

$= 29$

The required cumulative frequency table is given below:
