Solution

First, arranging the given data in ascending order.
4, 5, 7, 7, 13, 15, 16, 16, 17, 17, 19, 24, 25, 26, 27, 28, 30, 31, 31, 34, 34, 35, 35, 36, 36, 36,
42, 44, 45, 47, 48, 51, 52, 52, 54, 55, 55, 56, 56, 61, 62, 62, 63, 68, 70, 72, 72, 72, 74, 75,
75, 78, 80, 81, 85, 86, 86, 92, 95, 97
We arrange the given data into groups like 0-9, 10-19, 20-29, … The class width in each case is 10.
The frequency distribution of the given data is given below.
