## Description

Everything is listed below! if you have any questions please ask.

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

Economic | Population Exposed to Risk | Number of Deaths | Deaths per 100 Exposed to Risk | ||||||

Adult | Child | Both | Adult | Child | Both | Adult | Child | Both | |

I and II | 560 | 19 | 579 | 280 | 0 | 280 | 50 | 0 | 48 |

Total | 1237 | 86 | 1323 | 770 | 49 | 819 | 62 | 57 | 62 |

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

- Is there a difference in the probability of death for males vs. females?
- Does age make a difference in the probability of death?
- What does the number of children in relation to the number of adults tell you about this population?
- Does economic status make a difference in the probability of death? Does your answer to this question differ depending on the subgroup you are looking at?
- What other questions would you like to ask about these data or this event in order to help you make a determination? Can you guess what event generated this data?

We seek well-reasoned hypotheses about the cause of the event **based** **on the given data**. With this in mind, please **do not** search the internet looking for the answer. Incorrect guesses based on sound, logical thinking will be graded favorably.

QUESTION 1:

We know that out of 857 males, 688 died. 688/857 = 0,8028, or 80%. On the other side,

out of 466 females, only 131 died, so 131/466 = 0,2811, or 28%. T...
