Data, Sampling, and Variation in Data and Sampling · Exercise 6

contains the total number of deaths worldwide as a result of earthquakes from 2000–2012.

$$\begin{array}{cc}\text{Year}& \text{Total Number of Deaths}\\ \text{2000}& \text{231}\\ \text{2001}& \text{21,357}\\ \text{2002}& \text{11,685}\\ \text{2003}& \text{33,819}\\ \text{2004}& \text{228,802}\\ \text{2005}& \text{88,003}\\ \text{2006}& \text{6,605}\\ \text{2007}& \text{712}\\ \text{2008}& \text{88,011}\\ \text{2009}& \text{1,790}\\ \text{2010}& \text{320,120}\\ \text{2011}& \text{21,953}\\ \text{2012}& \text{768}\\ \text{Total}& \text{823,856}\end{array}$$
Use to answer the following questions.

(a) What is the proportion of deaths between 2007–2012?
(b) What percent of deaths occurred before 2001?
(c) What is the percent of deaths that occurred in 2003 or after 2010?
(d) What is the fraction of deaths that happened before 2012?
(e) What kind of data is the number of deaths?
(f) 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?
(g) What contributed to the large number of deaths in 2010? In 2004? Explain.
(h) If you were asked to present these data in an oral presentation, what type of graph would you choose to present and why? Explain what features you would point out on the graph during your presentation.
