Being able to draw probability conclusions from data is important. This data has a great deal of information.
For example, on the table titled “By Economic Status and Sex,” looking at the total male population exposed to risk, there were 857 males. Looking at the same table, 688 of those males died. The proportion of males exposed to risk that died is 688/857=0.80. Thus, among the males exposed to risk, there are 80 deaths per 100.
By the end of this discussion, you will have demonstrated your ability to:
• Analyze and interpret data
• Calculate probabilities given raw data

Refer to the data tables above and answer the following questions. Be sure to support your answers (e.g. provide probabilities, ratios, etc.).

1. Is there a difference in the probability of death for males vs. females?
2. Does age make a difference in the probability of death?
