Question

the following is the distribution of weights in kg of 50 persons
weight {in kg}/no. of persons
50-55/10,55-60/8,60-65/7,65-70/4,70-75/9,75-80/3,80-85/6,85-90/3
draw a histogram to represent the above data​

Answer 1

$\text{Using the following scale, I have drawn a historam }$

$\text{to represent the given data}$

$\textsf{Scale:}$

$\textsf{X axis: 1 cm = 5 units}$

$\textsf{Y axis: 1 cm = 1 unit}$

Answer 2

Given:

weight {in kg}/no. of persons

50-55/10,55-60/8,60-65/7,65-70/4,70-75/9,75-80/3,80-85/6,85-90/3

To find:

To draw a histogram to represent the above data​.

Solution:

First we need to construct a table.

Weight (kg)          No. of persons

50 - 55                        10

55 - 60                        8

60 - 65                        7

65 - 70                        4

70 - 75                        9

75 - 80                        3

80 - 85                        6

85 - 90                        3

x-axis represents the weight of students in kg.

x-axis: 1 cm = 5 units

y-axis represents the number of students.

y-axis: 1 cm = 2.5 units

The histogram to represent the above data​ is attached below.
