Answer #1

Solution:

Given:

Country Frequency
American 20
Australian 35
Pakistanis 22
Indians 40
N = 117

To create Pie chart, we need to find angle of each sector.

Formula:

Frequency x 360° 0° =-  

Country Frequency Percentage θo
American 20 17% 62o
Australian 35 30% 108o
Pakistanis 22 19% 68o
Indians 40 34% 123o
N =117 Total Degree =360o

Draw a circle.

Draw sector of each angle shown in above table.

Write the labels of each sector by country name and its frequency.

We can use percentage of each country to show it in Pie chart.

Pie Chart Indians, 40, 34% American, 20, 17% 108 62° 680 1230 Pakistanis, 22, 19% Austrilian, 35, 30%
