Question
Chapter 3, Problem 11E
(a)
To determine
To find: that is it reasonable to conclude heart or respiratory diseases.
(a)
Expert Solution
Answer to Problem 11E
Reasonable
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 |
Only one cause of death of every patient that is no patient has more than one reason of death. It means there is no category overlap so relative frequencies could be added. For the deaths cause by the heart or respiratory disease is
27.2% + 5.1% = 33% (approximately)
Therefore it is reasonable to conclude that respiratory or hear diseases were the cause of about 33% of U.S. deaths in 2003
(b)
To determine
To find: the percent of death were from causes not listed here.
(b)
Expert Solution
Answer to Problem 11E
66.4%
Explanation of Solution
Total percent of deaths by the causes is
27.2% + 23.1% + 6.3% +5.1% 4.7% = 66.4%
Therefore, the percent of deaths from causes not listed here
100% - 66.4% = 33.6%
(c)
To determine
To Explain: an appropriate represent for these data.
(c)
Expert Solution
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.
