Answer to Problem 11E

Bar chart

Explanation of Solution

Given:

Cause of Death	Percent
Heart disease	27.2
Cancer	23.1
Circulatory diseases and stroke	6.3
Respiratory diseases	5.1
Accidents	4.7
Others	66.4

Graph:

  

There is total addition of the number is 100 percent so the bar chart would be good to use.
