Use the following information to answer the next four exercises: A study was done to determine the age, number of times per week, and the duration (amount of time) of residents using a local park in San Antonio, Texas. The first house in the neighborhood around the park was selected randomly, and then the resident of every eighth house in the neighborhood around the park was interviewed.
the table contains the total number of deaths worldwide as a result of earthquakes over a 13-year period.
| Year | Total Number of Deaths |
| 1 | 231 |
| 2 | 21,357 |
| 3 | 11,685 |
| 4 | 33,819 |
| 5 | 228,802 |
| 6 | 88,003 |
| 7 | 6,605 |
| 8 | 712 |
| 9 | 88,011 |
| 10 | 1,790 |
| 11 | 320,120 |
| 12 | 21,953 |
| 13 | 768 |
| Total | 823,856 |
Use the table to answer the following questions.
- What is the proportion of deaths between Year 8 and Year 13?
- What percent of deaths occurred before Year 2?
- What is the percent of deaths that occurred in Year 4 or after Year 11?
- What is the fraction of deaths that happened before Year 13?
- What kind of data is the number of deaths?
- Earthquakes are quantified according to the amount of energy they produce (examples are 2.1, 5.0, 6.7). What type of data is that?
- What contributed to the large number of deaths in Year 11? In Year 5? Explain.
