Is it reasonable to conclude that, in this state, cancer or respiratory diseases were the cause of approximately 28% of deaths in 2002?

Cause of death Percent
Heart disease 28.4
Cancer 21.4
Circulatory disease 7.6
Respiratory Diseases 6.4
Accidents 4.9

Your table says 29% (21.4% + 7.6%). Is that "approxinately" 28%? I would say yes.
