    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

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)
